Enum Wtf8 

pub enum Wtf8 {}

The WTF-8 encoding: arbitrary, ill-formed-tolerant WTF-8 stored as u8 code units – the byte representation a Windows OsStr uses.

It matches OsString’s WTF-8 layout but is not built on OsString (D-3): the storage is a crate-owned Vec<u8>. Construction from units performs no validation, so the bytes may be well-formed WTF-8 (including encoded surrogates) or arbitrary. Like Wtf16 it is a pure type-level marker and is never constructed.

Trait Implementations

impl WtfEncoding for Wtf8

const NUL: u8 = 0

The NUL code unit (U+0000) used as the always-present buffer terminator.

type Unit = u8

The code unit this encoding stores (u16 for Wtf16).

fn encode_str(s: &str) -> Vec<u8>

Encode a UTF-8 str into this encoding’s code units.

fn decode(units: &[u8]) -> Option<String>

Decode content code units to a String if they are well-formed for this encoding, or None if they are ill-formed (e.g. an unpaired surrogate), which a strict String cannot represent.

fn decode_lossy(units: &[u8]) -> String

Decode content code units to a String, replacing any ill-formed sequence with the Unicode replacement character (U+FFFD).

fn eq_str(units: &[u8], s: &str) -> bool

Whether content code units equal the UTF-8 str s under this encoding.

fn debug_fmt(units: &[u8], f: &mut Formatter<'_>) -> Result

Write the escaped debug form of units, like OsStr: quoted, with control and non-printable characters escaped.
