Reads on any AsyncBufRead: up to a delimiter, a line, the lines or the segments one by one.

Provided Methods

fn read_until<'a>( &'a mut self, byte: u8, buf: &'a mut Vec<u8>, ) -> ReadUntil<'a, Self>

where Self: Unpin,

Reads up to and including byte (or to the end), appending to buf; answers how many bytes it appended (0 at the end).

fn read_line<'a>(&'a mut self, buf: &'a mut String) -> ReadLine<'a, Self>

where Self: Unpin,

Reads up to and including a newline (or to the end), appending to buf if what it read is UTF-8 (an InvalidData error and buf as it was otherwise); answers how many bytes it appended (0 at the end).

fn lines(self) -> Lines<Self>

where Self: Sized,

The lines, without their \n or \r\n, one by one through Lines::next_line.

fn split(self, byte: u8) -> Split<Self>

where Self: Sized,

The segments between bytes, without it, one by one through Split::next_segment.

fn fill_buf(&mut self) -> FillBuf<'_, Self>

where Self: Unpin,

The reader’s buffer, filled if it was empty (empty at the end).

fn consume(&mut self, amount: usize)

where Self: Unpin,

Marks amount bytes of the buffer read.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
