Expand description

Reads on any AsyncRead: into a slice, a ReadBuf, to the end, as typed numbers in big or little endian.

Provided Methods§

Source

fn read<'a>(&'a mut self, buf: &'a mut [u8]) -> Read<'a, Self> ⓘ
where Self: Unpin,

Reads some bytes into buf, answering how many (0 at the end).

Source

fn read_buf<'a, 'b>( &'a mut self, buf: &'a mut ReadBuf<'b>, ) -> ReadBufFuture<'a, 'b, Self> ⓘ
where Self: Unpin,

Reads some bytes into the unfilled part of buf and counts them filled, answering how many (0 at the end, or when buf is full).

Source

fn read_exact<'a>(&'a mut self, buf: &'a mut [u8]) -> ReadExact<'a, Self> ⓘ
where Self: Unpin,

Fills buf exactly, answering its length; an end of the stream first is an UnexpectedEof error.

Source

fn read_to_end<'a>(&'a mut self, buf: &'a mut Vec<u8>) -> ReadToEnd<'a, Self> ⓘ
where Self: Unpin,

Reads to the end of the stream, appending to buf; answers how many bytes it appended.

Source

fn read_to_string<'a>( &'a mut self, buf: &'a mut String, ) -> ReadToString<'a, Self> ⓘ
where Self: Unpin,

Reads to the end of the stream, 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.
