-//
-// (10 * p2) div 2^-e = d[-1]
-// (10 * p2) mod 2^-e = d[-2] / 10^1 + ...
-//
-// The multiplication by 10 must not overflow. It is sufficient to choose

-@brief exception indicating a parse error
-
-This exception is thrown by the library when a parse error occurs. Parse errors
-can occur during the deserialization of JSON text, CBOR, MessagePack, as well
-as when using JSON Patch.
-
-Member @a byte holds the byte index of the last read character in the input
-file.
-
-Exceptions have ids 1xx.
-
-name / id | example message | description
------------------------------- | --------------- | -------------------------
-json.exception.parse_error.101 | parse error at 2: unexpected end of input; expected string literal | This error indicates a syntax error while deserializing a JSON text. The error message describes that an unexpected token (character) was encountered, and the member @a byte indicates the error position.
-json.exception.parse_error.102 | parse error at 14: missing or wrong low surrogate | JSON uses the `\uxxxx` format to describe Unicode characters. Code points above above 0xFFFF are split into two `\uxxxx` entries ("surrogate pairs"). This error indicates that the surrogate pair is incomplete or contains an invalid code point.
-json.exception.parse_error.103 | parse error: code points above 0x10FFFF are invalid | Unicode supports code points up to 0x10FFFF. Code points above 0x10FFFF are invalid.
-json.exception.parse_error.104 | parse error: JSON patch must be an array of objects | [RFC 6902](https://tools.ietf.org/html/rfc6902) requires a JSON Patch document to be a JSON document that represents an array of objects.
-json.exception.parse_error.105 | parse error: operation must have string member 'op' | An operation of a JSON Patch document must contain exactly one "op" member, whose value indicates the operation to perform. Its value must be one of "add", "remove", "replace", "move", "copy", or "test"; other values are errors.
-json.exception.parse_error.106 | parse error: array index '01' must not begin with '0' | An array index in a JSON Pointer ([RFC 6901](https://tools.ietf.org/html/rfc6901)) may be `0` or any number without a leading `0`.
-json.exception.parse_error.107 | parse error: JSON pointer must be empty or begin with '/' - was: 'foo' | A JSON Pointer must be a Unicode string containing a sequence of zero or more reference tokens, each prefixed by a `/` character.
-json.exception.parse_error.108 | parse error: escape character '~' must be followed with '0' or '1' | In a JSON Pointer, only `~0` and `~1` are valid escape sequences.
-json.exception.parse_error.109 | parse error: array index 'one' is not a number | A JSON Pointer array index must be a number.
-json.exception.parse_error.110 | parse error at 1: cannot read 2 bytes from vector | When parsing CBOR or MessagePack, the byte vector ends before the complete value has been read.
-json.exception.parse_error.112 | parse error at 1: error reading CBOR; last byte: 0xF8 | Not all types of CBOR or MessagePack are supported. This exception occurs if an unsupported byte was read.
-json.exception.parse_error.113 | parse error at 2: expected a CBOR string; last byte: 0x98 | While parsing a map key, a value that is not a string has been read.
-json.exception.parse_error.114 | parse error: Unsupported BSON record type 0x0F | The parsing of the corresponding BSON record type is not implemented (yet).
-
-@note For an input with n bytes, 1 is the index of the first character and n+1
- is the index of the terminating null byte or the end of file. This also
- holds true when reading a byte vector (CBOR or MessagePack).

-json.exception.invalid_iterator.202 | iterator does not fit current value | In an erase or insert function, the passed iterator @a pos does not belong to the JSON value for which the function was called. It hence does not define a valid position for the deletion/insertion.
-json.exception.invalid_iterator.203 | iterators do not fit current value | Either iterator passed to function @ref erase(IteratorType first, IteratorType last) does not belong to the JSON value from which values shall be erased. It hence does not define a valid range to delete values from.
-json.exception.invalid_iterator.204 | iterators out of range | When an iterator range for a primitive type (number, boolean, or string) is passed to a constructor or an erase function, this range has to be exactly (@ref begin(), @ref end()), because this is the only way the single stored value is expressed. All other ranges are invalid.
-json.exception.invalid_iterator.205 | iterator out of range | When an iterator for a primitive type (number, boolean, or string) is passed to an erase function, the iterator has to be the @ref begin() iterator, because it is the only way to address the stored value. All other iterators are invalid.
-json.exception.invalid_iterator.206 | cannot construct with iterators from null | The iterators passed to constructor @ref basic_json(InputIT first, InputIT last) belong to a JSON null value and hence to not define a valid range.
-json.exception.invalid_iterator.207 | cannot use key() for non-object iterators | The key() member function can only be used on iterators belonging to a JSON object, because other types do not have a concept of a key.
-json.exception.invalid_iterator.208 | cannot use operator[] for object iterators | The operator[] to specify a concrete offset cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.209 | cannot use offsets with object iterators | The offset operators (+, -, +=, -=) cannot be used on iterators belonging to a JSON object, because JSON objects are unordered.
-json.exception.invalid_iterator.210 | iterators do not fit | The iterator range passed to the insert function are not compatible, meaning they do not belong to the same container. Therefore, the range (@a first, @a last) is invalid.
-json.exception.invalid_iterator.211 | passed iterators may not belong to container | The iterator range passed to the insert function must not be a subrange of the container to insert to.
-json.exception.invalid_iterator.212 | cannot compare iterators of different containers | When two iterators are compared, they must belong to the same container.
-json.exception.invalid_iterator.213 | cannot compare order of object iterators | The order of object iterators cannot be compared, because JSON objects are unordered.
-json.exception.invalid_iterator.214 | cannot get value | Cannot get value for iterator: Either the iterator belongs to a null value or it is an iterator to a primitive type (number, boolean, or string), but the iterator is different to @ref begin().

- @brief scan a number literal
-
- This function scans a string according to Sect. 6 of RFC 7159.
-
- The function is realized with a deterministic finite state machine derived
- from the grammar described in RFC 7159. Starting in state "init", the
- input is read and used to determined the next state. Only state "done"
- accepts the number. State "error" is a trap state to model errors. In the
- table below, "anything" means any character but the ones listed before.
-
- state | 0 | 1-9 | e E | + | - | . | anything
- ---------|----------|----------|----------|---------|---------|----------|-----------
- init | zero | any1 | [error] | [error] | minus | [error] | [error]
- minus | zero | any1 | [error] | [error] | [error] | [error] | [error]
- zero | done | done | exponent | done | done | decimal1 | done
- any1 | any1 | any1 | exponent | done | done | decimal1 | done
- decimal1 | decimal2 | [error] | [error] | [error] | [error] | [error] | [error]
- decimal2 | decimal2 | decimal2 | exponent | done | done | done | done
- exponent | any2 | any2 | [error] | sign | sign | [error] | [error]
- sign | any2 | any2 | [error] | [error] | [error] | [error] | [error]
- any2 | any2 | any2 | done | done | done | done | done
-
- The state machine is realized with one label per state (prefixed with
- "scan_number_") and `goto` statements between them. The state machine
- contains cycles, but any cycle can be left when EOF is read. Therefore,
- the function is guaranteed to terminate.
-
- During scanning, the read bytes are stored in token_buffer. This string is
- then converted to a signed integer, an unsigned integer, or a
- floating-point number.
-
- @return token_type::value_unsigned, token_type::value_integer, or
- token_type::value_float if number could be successfully scanned,
- token_type::parse_error otherwise
-
- @note The scanner is independent of the current locale. Internally, the
- locale's decimal point is used instead of `.` to work with the
- locale-dependent converters.

-@brief a template for a bidirectional iterator for the @ref basic_json class
-
-This class implements a both iterators (iterator and const_iterator) for the
-@ref basic_json class.
-
-@note An iterator is called *initialized* when a pointer to a JSON value has
- been set (e.g., by a constructor or a copy assignment). If the iterator is
- default-constructed, it is *uninitialized* and most methods are undefined.
- **The library uses assertions to detect calls on uninitialized iterators.**
-
-@requirement The class satisfies the following concept requirements:
--
-[BidirectionalIterator](https://en.cppreference.com/w/cpp/named_req/BidirectionalIterator):
- The iterator that can be moved can be moved in both directions (i.e.
- incremented and decremented).
-
-@since version 1.0.0, simplified in version 2.0.9, change to bidirectional
- iterators in version 3.0.0 (see https://github.com/nlohmann/json/issues/593)

-@brief the JSON type enumeration
-
-This enumeration collects the different JSON types. It is internally used to
-distinguish the stored values, and the functions @ref basic_json::is_null(),
-@ref basic_json::is_object(), @ref basic_json::is_array(),
-@ref basic_json::is_string(), @ref basic_json::is_boolean(),
-@ref basic_json::is_number() (with @ref basic_json::is_number_integer(),
-@ref basic_json::is_number_unsigned(), and @ref basic_json::is_number_float()),
-@ref basic_json::is_discarded(), @ref basic_json::is_primitive(), and
-@ref basic_json::is_structured() rely on it.
-
-@note There are three enumeration entries (number_integer, number_unsigned, and
-number_float), because the library distinguishes these three types for numbers:
-@ref basic_json::number_unsigned_t is used for unsigned integers,
-@ref basic_json::number_integer_t is used for signed integers, and
-@ref basic_json::number_float_t is used for floating-point numbers or to
-approximate integers which do not fit in the limits of their respective type.
-
-@sa @ref basic_json::basic_json(const value_t value_type) -- create a JSON
-value with the default value for a given type

-
-@requirement The class satisfies the following concept requirements:
-- Basic
- - [DefaultConstructible](https://en.cppreference.com/w/cpp/named_req/DefaultConstructible):
- JSON values can be default constructed. The result will be a JSON null
- value.
- - [MoveConstructible](https://en.cppreference.com/w/cpp/named_req/MoveConstructible):
- A JSON value can be constructed from an rvalue argument.
- - [CopyConstructible](https://en.cppreference.com/w/cpp/named_req/CopyConstructible):
- A JSON value can be copy-constructed from an lvalue expression.
- - [MoveAssignable](https://en.cppreference.com/w/cpp/named_req/MoveAssignable):
- A JSON value van be assigned from an rvalue argument.
- - [CopyAssignable](https://en.cppreference.com/w/cpp/named_req/CopyAssignable):
- A JSON value can be copy-assigned from an lvalue expression.
- - [Destructible](https://en.cppreference.com/w/cpp/named_req/Destructible):
- JSON values can be destructed.
-- Layout
- - [StandardLayoutType](https://en.cppreference.com/w/cpp/named_req/StandardLayoutType):
- JSON values have
- [standard layout](https://en.cppreference.com/w/cpp/language/data_members#Standard_layout):
- All non-static data members are private and standard layout types, the
- class has no virtual functions or (virtual) base classes.
-- Library-wide
- - [EqualityComparable](https://en.cppreference.com/w/cpp/named_req/EqualityComparable):
- JSON values can be compared with `==`, see @ref
- operator==(const_reference,const_reference).
- - [LessThanComparable](https://en.cppreference.com/w/cpp/named_req/LessThanComparable):
- JSON values can be compared with `<`, see @ref
- operator<(const_reference,const_reference).
- - [Swappable](https://en.cppreference.com/w/cpp/named_req/Swappable):
- Any JSON lvalue or rvalue of can be swapped with any lvalue or rvalue of
- other compatible types, using unqualified function call @ref swap().
- - [NullablePointer](https://en.cppreference.com/w/cpp/named_req/NullablePointer):
- JSON values can be compared against `std::nullptr_t` objects which are used
- to model the `null` value.
-- Container
- - [Container](https://en.cppreference.com/w/cpp/named_req/Container):
- JSON values can be used like STL containers and provide iterator access.
- - [ReversibleContainer](https://en.cppreference.com/w/cpp/named_req/ReversibleContainer);
- JSON values can be used like STL containers and provide reverse iterator
- access.
-
-@invariant The member variables @a m_value and @a m_type have the following
-relationship:
-- If `m_type == value_t::object`, then `m_value.object != nullptr`.
-- If `m_type == value_t::array`, then `m_value.array != nullptr`.
-- If `m_type == value_t::string`, then `m_value.string != nullptr`.
-The invariants are checked by member function assert_invariant().

- /*!
- @brief a type for an object
-
- [RFC 7159](http://rfc7159.net/rfc7159) describes JSON objects as follows:
- > An object is an unordered collection of zero or more name/value pairs,
- > where a name is a string and a value is a string, number, boolean, null,
- > object, or array.
-
- To store objects in C++, a type is defined by the template parameters
- described below.
-
- @tparam ObjectType the container to store objects (e.g., `std::map` or
- `std::unordered_map`)
- @tparam StringType the type of the keys or names (e.g., `std::string`).
- The comparison function `std::less<StringType>` is used to order elements
- inside the container.
- @tparam AllocatorType the allocator to use for objects (e.g.,
- `std::allocator`)
-
- #### Default type
-
- With the default values for @a ObjectType (`std::map`), @a StringType
- (`std::string`), and @a AllocatorType (`std::allocator`), the default
- value for @a object_t is:
-
- @code {.cpp}
- std::map<
- std::string, // key_type
- basic_json, // value_type
- std::less<std::string>, // key_compare
- std::allocator<std::pair<const std::string, basic_json>> // allocator_type
- >
- @endcode
-
- #### Behavior
-
- The choice of @a object_t influences the behavior of the JSON class. With
- the default type, objects have the following behavior:
-
- - When all names are unique, objects will be interoperable in the sense
- that all software implementations receiving that object will agree on
- the name-value mappings.
- - When the names within an object are not unique, it is unspecified which
- one of the values for a given key will be chosen. For instance,
- `{"key": 2, "key": 1}` could be equal to either `{"key": 1}` or
- `{"key": 2}`.
- - Internally, name/value pairs are stored in lexicographical order of the
- names. Objects will also be serialized (see @ref dump) in this order.
- For instance, `{"b": 1, "a": 2}` and `{"a": 2, "b": 1}` will be stored
- and serialized as `{"a": 2, "b": 1}`.
- - When comparing objects, the order of the name/value pairs is irrelevant.
- This makes objects interoperable in the sense that they will not be
- affected by these differences. For instance, `{"b": 1, "a": 2}` and
- `{"a": 2, "b": 1}` will be treated as equal.
-
- #### Limits
-
- [RFC 7159](http://rfc7159.net/rfc7159) specifies:
- > An implementation may set limits on the maximum depth of nesting.
-
- In this class, the object's limit of nesting is not explicitly constrained.
- However, a maximum depth of nesting may be introduced by the compiler or
- runtime environment. A theoretical limit can be queried by calling the
- @ref max_size function of a JSON object.
-
- #### Storage
-
- Objects are stored as pointers in a @ref basic_json type. That is, for any
- access to object values, a pointer of type `object_t*` must be
- dereferenced.
-
- @sa @ref array_t -- type for an array value
-
- @since version 1.0.0
-
- @note The order name/value pairs are added to the object is *not*
- preserved by the library. Therefore, iterating an object may return
- name/value pairs in a different order than they were originally stored. In
- fact, keys will be traversed in alphabetical order as `std::map` with
- `std::less` is used by default. Please note this behavior conforms to [RFC
- 7159](http://rfc7159.net/rfc7159), because any order implements the
- specified "unordered" nature of JSON objects.

- @tparam StringType the container to store strings (e.g., `std::string`).
- Note this container is used for keys/names in objects, see @ref object_t.

- #### Default type
-
- With the default values for @a StringType (`std::string`), the default
- value for @a string_t is:
-
- @code {.cpp}

-
- #### Encoding
-
- Strings are stored in UTF-8 encoding. Therefore, functions like
- `std::string::size()` or `std::string::length()` return the number of
- bytes in the string rather than the number of characters or glyphs.
-
- #### String comparison
-
- [RFC 7159](http://rfc7159.net/rfc7159) states:
- > Software implementations are typically required to test names of object
- > members for equality. Implementations that transform the textual
- > representation into sequences of Unicode code units and then perform the
- > comparison numerically, code unit by code unit, are interoperable in the
- > sense that implementations will agree in all cases on equality or
- > inequality of two strings. For example, implementations that compare
- > strings with escaped characters unconverted may incorrectly find that
- > `"a\\b"` and `"a\u005Cb"` are not equal.
-
- This implementation is interoperable as it does compare strings code unit
- by code unit.
-
- #### Storage
-
- String values are stored as pointers in a @ref basic_json type. That is,
- for any access to string values, a pointer of type `string_t*` must be
- dereferenced.

- This description includes both integer and floating-point numbers.
- However, C++ allows more precise storage if it is known whether the number

- #### Limits
-
- [RFC 7159](http://rfc7159.net/rfc7159) specifies:

- @brief create a container (array or object) from an initializer list
-
- Creates a JSON value of type array or object from the passed initializer
- list @a init. In case @a type_deduction is `true` (default), the type of
- the JSON value to be created is deducted from the initializer list @a init
- according to the following rules:
-
- 1. If the list is empty, an empty JSON object value `{}` is created.
- 2. If the list consists of pairs whose first element is a string, a JSON
- object value is created where the first elements of the pairs are
- treated as keys and the second elements are as values.
- 3. In all other cases, an array is created.
-
- The rules aim to create the best fit between a C++ initializer list and
- JSON values. The rationale is as follows:
-
- 1. The empty initializer list is written as `{}` which is exactly an empty
- JSON object.
- 2. C++ has no way of describing mapped types other than to list a list of
- pairs. As JSON requires that keys must be of type string, rule 2 is the
- weakest constraint one can pose on initializer lists to interpret them
- as an object.
- 3. In all other cases, the initializer list could not be interpreted as
- JSON object type, so interpreting it as JSON array type is safe.
-
- With the rules described above, the following JSON values cannot be
- expressed by an initializer list:
-
- - the empty array (`[]`): use @ref array(initializer_list_t)
- with an empty initializer list in this case
- - arrays whose elements satisfy rule 2: use @ref
- array(initializer_list_t) with the same initializer list
- in this case
-
- @note When used without parentheses around an empty initializer list, @ref
- basic_json() is called instead of this function, yielding the JSON null
- value.
-
- @param[in] init initializer list with JSON values
-
- @param[in] type_deduction internal parameter; when set to `true`, the type
- of the JSON value is deducted from the initializer list @a init; when set
- to `false`, the type provided via @a manual_type is forced. This mode is
- used by the functions @ref array(initializer_list_t) and
- @ref object(initializer_list_t).
-
- @param[in] manual_type internal parameter; when @a type_deduction is set
- to `false`, the created JSON value will use the provided type (only @ref
- value_t::array and @ref value_t::object are valid); when @a type_deduction
- is set to `true`, this parameter has no effect
-
- @throw type_error.301 if @a type_deduction is `false`, @a manual_type is
- `value_t::object`, but @a init contains an element which is not a pair
- whose first element is a string. In this case, the constructor could not
- create an object. If @a type_deduction would have be `true`, an array
- would have been created. See @ref object(initializer_list_t)
- for an example.
-

- Also, integers larger than 9223372036854775807 cannot be serialized to BSON,

- @brief applies a JSON patch
-
- [JSON Patch](http://jsonpatch.com) defines a JSON document structure for
- expressing a sequence of operations to apply to a JSON) document. With
- this function, a JSON Patch is applied to the current JSON value by
- executing all operations from the patch.
-
- @param[in] json_patch JSON patch document
- @return patched document
-
- @note The application of a patch is atomic: Either all operations succeed
- and the patched document is returned or an exception is thrown. In
- any case, the original value is not changed: the patch is applied
- to a copy of the value.
-
- @throw parse_error.104 if the JSON patch does not consist of an array of
- objects
-
- @throw parse_error.105 if the JSON patch is malformed (e.g., mandatory
- attributes are missing); example: `"operation add must have member path"`
-
- @throw out_of_range.401 if an array index is out of range.
-
- @throw out_of_range.403 if a JSON pointer inside the patch could not be
- resolved successfully in the current JSON value; example: `"key baz not
- found"`
-
- @throw out_of_range.405 if JSON pointer has no parent ("add", "remove",
- "move")
-
- @throw other_error.501 if "test" operation was unsuccessful
-
- @complexity Linear in the size of the JSON value and the length of the
- JSON patch. As usually only a fraction of the JSON value is affected by
- the patch, the complexity can usually be neglected.

- * Definition of inline macros.
- *
- * MPack does not use static inline in header files; only one non-inline definition
- * of each function should exist in the final build. This can reduce the binary size
- * in cases where the compiler cannot or chooses not to inline a function.
- * The addresses of functions should also compare equal across translation units
- * regardless of whether they are declared inline.
- *
- * The above requirements mean that the declaration and definition of non-trivial
- * inline functions must be separated so that the definitions will only
- * appear when necessary. In addition, three different linkage models need
- * to be supported:
- *
- * - The C99 model, where a standalone function is emitted only if there is any
- * `extern inline` or non-`inline` declaration (including the definition itself)
- *
- * - The GNU model, where an `inline` definition emits a standalone function and an
- * `extern inline` definition does not, regardless of other declarations
- *
- * - The C++ model, where `inline` emits a standalone function with special
- * (COMDAT) linkage
- *
- * The macros below wrap up everything above. All inline functions defined in header
- * files have a single non-inline definition emitted in the compilation of
- * mpack-platform.c. All inline declarations and definitions use the same MPACK_INLINE
- * specification to simplify the rules on when standalone functions are emitted.
- * Inline functions in source files are defined MPACK_STATIC_INLINE.
- *
- * Additional reading:
- * http://www.greenend.org.uk/rjk/tech/inline.html

- * always fatal.
- *
- * In release mode, mpack_assert() is converted to an assurance to the compiler
- * that the expression cannot be false (via e.g. __assume() or __builtin_unreachable())
- * to improve optimization where supported. There is thus no point in "safely" handling
- * the case of this being false. Writing mpack_assert(0) rarely makes sense (except
- * possibly as a default handler in a switch) since the compiler will throw away any
- * code after it. If at any time an mpack_assert() is not true, the behaviour is
- * undefined. This also means the expression is evaluated even in release.
- *
- * mpack_break() on the other hand is compiled to nothing in release. It is
- * used in situations where we want to highlight a programming error as early as
- * possible (in the debugger), but we still handle the situation safely if it
- * happens in release to avoid producing incorrect results (such as in
- * MPACK_WRITE_TRACKING.) It does not take an expression to test because it
- * belongs in a safe-handling block after its failing condition has been tested.
- *
- * If stdio is available, we can add a format string describing the error, and
- * on some compilers we can declare it noreturn to get correct results from static
- * analysis tools. Note that the format string and arguments are not evaluated unless
- * the assertion is hit.
- *
- * Note that any arguments to mpack_assert() beyond the first are only evaluated
- * if the expression is false (and are never evaluated in release.)
- *
- * mpack_assert_fail() and mpack_break_hit() are defined separately
- * because assert is noreturn and break isn't. This distinction is very
- * important for static analysis tools to give correct results.

- * @defgroup expect Expect API
- *
- * The MPack Expect API allows you to easily read MessagePack data when you
- * expect it to follow a predefined schema.
- *
- * @note If you are not writing code for an embedded device (or otherwise do
- * not need maximum performance with minimal memory usage), you should not use
- * this. You probably want to use the @link node Node API@endlink instead.
- *
- * See @ref docs/expect.md for examples.
- *
- * The main purpose of the Expect API is convenience, so the API is lax. It
- * automatically converts between similar types where there is no loss of
- * precision.
- *
- * When using any of the expect functions, if the type or value of what was
- * read does not match what is expected, @ref mpack_error_type is raised.
