source§fn fill_buf(&mut self) -> FillBuf<'_, Self> ⓘwhere
Self: Unpin,
fn fill_buf(&mut self) -> FillBuf<'_, Self> ⓘwhere Self: Unpin,
Creates a future which will wait for a non-empty buffer to be available from this I/O
object or EOF to be reached. Read more

Self: Unpin,
fn read_until<'a>( &'a mut self, byte: u8, buf: &'a mut Vec<u8> ) -> ReadUntil<'a, Self> ⓘwhere Self: Unpin,
Creates a future which will read all the bytes associated with this I/O
object into
buf
until the delimiter byte
or EOF is reached.
This method is the async equivalent to BufRead::read_until

Self: Unpin,
fn read_line<'a>(&'a mut self, buf: &'a mut String) -> ReadLine<'a, Self> ⓘwhere Self: Unpin,
Creates a future which will read all the bytes associated with this I/O
object into
buf
until a newline (the 0xA byte) or EOF is reached,
This method is the async equivalent to BufRead::read_line

fn chain<R>(self, next: R) -> Chain<Self, R>where Self: Sized, R: AsyncRead,
Creates an adaptor which will chain this stream with another. Read more

Self: Unpin,
fn read<'a>(&'a mut self, buf: &'a mut [u8]) -> Read<'a, Self> ⓘwhere Self: Unpin,
Tries to read some bytes directly into the given
buf
in asynchronous
manner, returning a future type. Read moresource§fn read_vectored<'a>(
&'a mut self,
bufs: &'a mut [IoSliceMut<'a>]
) -> ReadVectored<'a, Self> ⓘwhere
Self: Unpin,
fn read_vectored<'a>( &'a mut self, bufs: &'a mut [IoSliceMut<'a>] ) -> ReadVectored<'a, Self> ⓘwhere Self: Unpin,
Creates a future which will read from the
AsyncRead
into bufs
using vectored
IO operations. Read moresource§fn read_exact<'a>(&'a mut self, buf: &'a mut [u8]) -> ReadExact<'a, Self> ⓘwhere
Self: Unpin,
fn read_exact<'a>(&'a mut self, buf: &'a mut [u8]) -> ReadExact<'a, Self> ⓘwhere Self: Unpin,
Creates a future which will read exactly enough bytes to fill
buf
,
returning an error if end of file (EOF) is hit sooner. Read moresource§fn read_to_end<'a>(&'a mut self, buf: &'a mut Vec<u8>) -> ReadToEnd<'a, Self> ⓘwhere
Self: Unpin,
fn read_to_end<'a>(&'a mut self, buf: &'a mut Vec<u8>) -> ReadToEnd<'a, Self> ⓘwhere Self: Unpin,
