- @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
-
- @since version 1.0.0

- @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 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 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.
-
- @param[in,out] state the state of the decoding
- @param[in,out] codep codepoint (valid only if resulting state is UTF8_ACCEPT)
- @param[in] byte next byte to decode
- @return new state
