+@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).
+json.exception.parse_error.115 | parse error at byte 5: syntax error while parsing UBJSON high-precision number: invalid number text: 1A | A UBJSON high-precision number could not be parsed.
+
+@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).

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.

+@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

+
+ 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 | decimal2 | [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.

+
+@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

+ /*!
+ @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.
