◆ pack_string()

void pack_string	(	std::string &	s,
		std::string_view	value
	)

inline

Append an encoded std::string to a string.

Parameters

s	The string to append to.
value	The std::string to encode.

Definition at line 442 of file pack.h.

References pack_uint().

◆ pack_string_empty()

void pack_string_empty ( std::string & s )

inline

Append an empty encoded std::string to a string.

This is equivalent to pack_string(s, ""sv) but is probably a bit more efficient.

Parameters

s	The string to append to.

Definition at line 456 of file pack.h.

◆ pack_string_preserving_sort()

void pack_string_preserving_sort	(	std::string &	s,
		std::string_view	value,
		bool	last = `false`
	)

inline

Append an encoded std::string to a string, preserving the sort order.

The byte which follows this encoded value must not be \xff, or the sort order won't be correct. You may need to store a padding byte (\0 say) to ensure this. Note that pack_uint_preserving_sort() can never produce \xff as its first byte so is safe to use immediately afterwards.

Parameters

s	The string to append to.
value	The std::string to encode.
last	If true, this is the last thing to be encoded in this string - see note below (default: false)

It doesn't make sense to use pack_string_preserving_sort() if nothing can ever follow, but if optional items can, you can set last=true in cases where nothing does and get a shorter encoding in those cases.

◆ pack_uint() [1/2]

template<>

void pack_uint	(	std::string &	s,

◆ pack_uint_last()

template<class U >

void pack_uint_last	(	std::string &	s,
		U	value
	)

inline

Append an encoded unsigned integer to a string as the last item.

This encoding is only suitable when this is the last thing encoded as the encoding used doesn't contain its own length.

Parameters

s	The string to append to.
value	The unsigned integer to encode.

Definition at line 100 of file pack.h.

◆ pack_uint_preserving_sort()

template<class U >

void pack_uint_preserving_sort	(	std::string &	s,
		U	value
	)

inline

Append an encoded unsigned integer to a string, preserving the sort order.

The appended string data will sort in the same order as the unsigned integer being encoded. The encoding used supports types up to 64-bit wide.

The most significant of the first byte are a series of 0-7 consecutive set bits followed by a clear bit. The number of set bits is 2 less than the total number of bytes in the encoded form. The value can be got by zeroing these leading set bits and then interpreting the bytes as a big-endian value (so except for the 9 byte encoded form, the lower order bits of the first byte give the most significant set byte of the value).

Values are encoded in the shortest way possible:

[0x00000000, 0x00007fff] 0AAAAAAA BBBBBBBB [0x00008000, 0x003fffff] 10AAAAAA BBBBBBBB CCCCCCCC [0x00400000, 0x1fffffff] 110AAAAA BBBBBBBB CCCCCCCC DDDDDDDD [0x20000000,0x0fffffffff] 1110AAAA BBBBBBBB CCCCCCCC DDDDDDDD EEEEEEEE

and so on with a full-64bit value encoding as 0b11111110 (0xfe) followed by the 8-byte big-endian representation:

11111110 AAAAAAAA BBBBBBBB CCCCCCCC ... HHHHHHHH

Note that the first byte of the encoding will never be \xff, so it is safe to store the result of this function immediately after the result of pack_string_preserving_sort().

Parameters

s	The string to append to.
value	The unsigned integer to encode.
