Traits

CollationKeySink

A std::io::Write-like trait for writing to a buffer-like object.

Functions

in_inclusive_range16 🔒

true iff i is greater or equal to start and less or equal to end.

split_prefix 🔒

Finds the identical prefix of left and right containing guaranteed well-format UTF-8.

split_prefix_latin1 🔒

Finds the identical prefix of left and right containing Latin1.

split_prefix_latin1_utf16 🔒

Finds the identical prefix of left containing Latin1 and right containing potentially ill-formed UTF-16.

split_prefix_u8 🔒

Finds the identical prefix of left and right containing potentially ill-formed UTF-8, while avoiding splitting a UTF-8 byte sequence. In case of ill-formed UTF-8, the prefix is not guaranteed to be maximal.

split_prefix_u16 🔒

Finds the identical prefix of left and right containing potentially ill-formed UTF-16, while avoiding splitting a well-formed surrogate pair. In case of ill-formed UTF-16, the prefix is not guaranteed to be maximal.

write_diff 🔒

write_identical_level 🔒
