unsigned int nlohmann::json_abi_v3_11_3::detail::serializer< BasicJsonType >::count_digits ( number_unsigned_t x )

[in] x unsigned integer number to count its digits

Returns: number of decimal digits

	)

inlinestaticprivatenoexcept

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 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.

Parameters

[in,out]	state	the state of the decoding
[in,out]	codep	codepoint (valid only if resulting state is UTF8_ACCEPT)
[in]	byte	next byte to decode

Returns: new state

Note: The function has been edited: a std::array is used.

internal implementation of the serialization function

This function is called by the public member function dump and organizes the serialization internally. The indentation level is propagated as additional parameter. In case of arrays and objects, the function is called recursively.

strings and object keys are escaped using escape_string()
integer numbers are converted implicitly via operator<<
floating-point numbers are converted to a string using "%g" format
binary values are serialized as objects containing the subtype and the byte array

Parameters

[in]	val	value to serialize
[in]	pretty_print	whether the output shall be pretty-printed
[in]	ensure_ascii	If ensure_ascii is true, all non-ASCII characters in the output are escaped with `\uXXXX` sequences, and the result consists of ASCII characters only.
[in]	indent_step	the indent level
[in]	current_indent	the current indent level (only used internally)

◆ dump_escaped()

template<typename BasicJsonType >

void nlohmann::json_abi_v3_11_3::detail::serializer< BasicJsonType >::dump_escaped	(	const string_t &	s,
		const bool	ensure_ascii
	)

inlineprivate

dump escaped string

Escape a string by replacing certain special characters by a sequence of an escape character (backslash) and another character and other control characters by a sequence of "\u" followed by a four-digit hex representation. The escaped string is written to output stream o.

Parameters

[in]	s	the string to escape
[in]	ensure_ascii	whether to escape non-ASCII characters with \uXXXX sequences

@complexity Linear in the length of string s.
