Struct grep_matcher::LineTerminator

pub struct LineTerminator(_);

A line terminator.

A line terminator represents the end of a line. Generally, every line is either "terminated" by the end of a stream or a specific byte (or sequence of bytes).

Generally, a line terminator is a single byte, specifically, \n, on Unix-like systems. On Windows, a line terminator is \r\n (referred to as CRLF for Carriage Return; Line Feed).

The default line terminator is \n on all platforms.

Methods

impl LineTerminator

pub fn byte(byte: u8) -> LineTerminator

Return a new single-byte line terminator. Any byte is valid.

pub fn crlf() -> LineTerminator

Return a new line terminator represented by \r\n.

When this option is used, consumers may generally treat a lone \n as a line terminator in addition to \r\n.

pub fn is_crlf(&self) -> bool

Returns true if and only if this line terminator is CRLF.

pub fn as_byte(&self) -> u8

Returns this line terminator as a single byte.

If the line terminator is CRLF, then this returns \n. This is useful for routines that, for example, find line boundaries by treating \n as a line terminator even when it isn't preceded by \r.

pub fn as_bytes(&self) -> &[u8]

Returns this line terminator as a sequence of bytes.

This returns a singleton sequence for all line terminators except for CRLF, in which case, it returns \r\n.

The slice returned is guaranteed to have length at least 1.
