Enum Encoding 

pub enum Encoding {
    Utf8,
    Utf8Bom,
    Utf16Le,
    Utf16Be,
}

The character encoding one document version is read in.

Variants

Utf8

UTF-8 with no byte-order mark and no NUL.

Utf8Bom

UTF-8 behind its byte-order mark.

Utf16Le

UTF-16, low byte first, behind its byte-order mark.

Utf16Be

UTF-16, high byte first, behind its byte-order mark.

Implementations

impl Encoding

pub fn of_mark(front: &[u8]) -> Encoding

The encoding the byte-order mark at the front of a version names, and UTF-8 when there is none. Reads at most the first three bytes, so a window of a stored version learns its encoding from them.

pub fn decode(self, bytes: &[u8]) -> Result<String, AxError>

The characters a stretch cut at character boundaries spells.

A mark at the front decodes as U+FEFF, the first character of the text (D5), so the text encodes back to exactly these bytes.

Errors

E_INVALID_ARGS naming the encoding when the bytes do not spell text in it.
