Enum LineEnding 

pub enum LineEnding {
    Lf,
    Crlf,
}

The line terminator a buffer was loaded with.

Variants

Lf

\n. The default for a new or newline-free file on every platform, including Windows — a file TYPE creates has no existing convention to honour, and LF is what the tools around it emit.

Crlf

\r\n.

Implementations

impl LineEnding

pub fn label(self) -> &'static str

What a status bar shows. The names every editor uses.

pub fn as_str(self) -> &'static str

The characters themselves, as save writes them.

pub fn detect(text: &str) -> Self

Detect from a file’s contents.

The first terminator decides. A mixed file is not a third kind of file: whatever line one did is what the file is, and it is what gets written back. Taking a majority instead would mean a save that silently rewrites every line break in somebody’s file because the count went the other way.

A lone \r is not a line ending. Classic Mac endings died with Mac OS 9 and a stray carriage return inside a line is far likelier, so treating one as a terminator would misread an ordinary file badly.
