Struct LineReader 

pub struct LineReader<R> { /* private fields */ }

A zero-copy & optimized line reader.

This reader recognizes both LF & CRLF line terminators, but not single CR.

Implementations

impl<R: Read> LineReader<R>

pub fn from_reader(inner: R) -> Self

Create a new reader with default using the provided reader implementing std::io::Read.

Avoid providing a buffered reader because buffering will be handled for you by the LineReader.

pub fn with_capacity(capacity: usize, inner: R) -> Self

Create a new reader with provided buffer capacity and using the provided reader implementing std::io::Read.

Avoid providing a buffered reader because buffering will be handled for you by the LineReader.

pub fn count_lines(&mut self) -> Result<u64>

Consume the reader to count the number of lines as fast as possible.

pub fn read_line(&mut self) -> Result<Option<&[u8]>>

Attempt to read the next line from underlying reader.

Will return None if the end of stream was reached.

pub fn position(&self) -> u64

Return the current byte offset of the reader.

pub fn into_bufreader(self) -> BufReader<R>

Return the underlying BufReader.

pub fn into_inner(self) -> R

Return the underlying reader.

BEWARE: Already buffered data will be lost!
