@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 see @ref basic_json::basic_json(const value_t value_type) -- create a JSON
value with the default value for a given type

@brief comparison operator for JSON types

Returns an ordering that is similar to Python:
- order: null < boolean < number < object < array < string < binary
- furthermore, each type is not smaller than itself
- discarded values are not comparable
- binary is represented as a b"" string in python and directly comparable to a
  string; however, making a binary array directly comparable with a string would
  be surprising behavior in a JSON file.

@brief SAX implementation to create a JSON value from SAX events

This class implements the @ref json_sax interface and processes the SAX events
to create a JSON value which makes it basically a DOM parser. The structure or
hierarchy of the JSON value is managed by the stack `ref_stack` which contains
a pointer to the respective array or object for each recursion depth.

After successful parsing, the value that is passed by reference to the
constructor contains the parsed value.

    @brief scan a number literal

    This function scans a string according to Sect. 6 of RFC 8259.

    The function is realized with a deterministic finite state machine derived
    from the grammar described in RFC 8259. 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.

/*!
@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 a template for a reverse iterator class

@tparam Base the base iterator type to reverse. Valid types are @ref
iterator (to create @ref reverse_iterator) and @ref const_iterator (to
create @ref const_reverse_iterator).

@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).
- [OutputIterator](https://en.cppreference.com/w/cpp/named_req/OutputIterator):
  It is possible to write to the pointed-to element (only if @a Base is
  @ref iterator).

@since version 1.0.0

// The idea is to cut the number c * w = f * 2^e into two parts, which can be

//
//      f * 2^e = ( (f div 2^-e) * 2^-e + (f mod 2^-e) ) * 2^e

//
// The conversion of p1 into decimal form requires a series of divisions and
// modulos by (a power of) 10. These operations are faster for 32-bit than for
// 64-bit integers, so p1 should ideally fit into a 32-bit integer. This can be
// achieved by choosing
//
//      -e >= 32   or   e <= -32 := gamma

//
//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
//
// into decimal form, the fraction is repeatedly multiplied by 10 and the digits
// d[-i] are extracted in order:
//
//      (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
//
//      10 * p2 < 16 * p2 = 2^4 * p2 <= 2^64.

    @brief check whether a string is UTF-8 encoded

    The function checks each byte of a string whether it is UTF-8 encoded. The
    result of the check is stored in the @a state parameter. The function must
    be called initially with state 0 (accept). State 1 means the string must
    be rejected, because the current byte is not allowed. If the string is
    completely processed, but the state is non-zero, the string ended
    prematurely; that is, the last byte indicated more bytes should have
    followed.

/*!
    @brief checks the class invariants

    This function asserts the class invariants. It needs to be called at the
    end of every constructor to make sure that created objects respect the
    invariant. Furthermore, it has to be called each time the type of a JSON
    value is changed, because the invariant expresses a relationship between
    @a m_type and @a m_value.

    Furthermore, the parent relation is checked for arrays and objects: If
    @a check_parents true and the value is an array or object, then the
    container's elements must have the current value as parent.

    @param[in] check_parents  whether the parent relation should be checked.
               The value is true by default and should only be set to false
               during destruction of objects when the invariant does not
               need to hold.
