Enum LineEnding 

pub enum LineEnding {
    Lf,
    CrLf,
}

How the lines of a delimited file end.

Measured, never assumed: LineEnding::of reads it off the file’s own bytes, and a file with no line break at all reads as LineEnding::Lf, which is what every engine reads by default.

Variants

Lf

A newline alone, \n: every system but Windows.

CrLf

A carriage return and then a newline, \r\n: a file written on Windows.

Implementations

impl LineEnding

pub fn of(text: &[u8]) -> Self

How the lines of this text end, decided by its first line break.

The first break ends the header row, so it is written the way the rest of the file is. Text with no newline at all is LineEnding::Lf.

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

The ending’s characters, as they stand in the file.

pub const fn escaped(self) -> &'static str

The ending spelled with backslashes, \n or \r\n: the two or four characters an engine that reads backslash escapes in a string literal takes for it. Put it inside the quotes of a record delimiter, on an engine that reads them that way.
