Struct Duplex

pub struct Duplex { /* private fields */ }

An AsyncRead + AsyncWrite stream, which reads from one ringbuffer, and writes to another.

Implementations

impl Duplex

pub fn pair(capacity: usize) -> (Duplex, Duplex)

Create a pair of duplex AsyncRead + AsyncWrite streams, for duplex communication between two entities (eg. client and server).

pub fn split(self) -> (Reader, Writer)

Split duplex AsyncRead + AsyncWrite stream into separate (AsyncRead, AsyncWrite) halves.

Trait Implementations

impl AsyncRead for Duplex

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &mut [u8], ) -> Poll<Result<usize>>

Attempt to read from the AsyncRead into buf.

fn poll_read_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &mut [IoSliceMut<'_>], ) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into bufs using vectored IO operations.

impl AsyncWrite for Duplex

fn poll_write( self: Pin<&mut Self>, cx: &mut Context<'_>, buf: &[u8], ) -> Poll<Result<usize>>

Attempt to write bytes from buf into the object.

fn poll_flush(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Result<()>>

Attempt to close the object.

fn poll_write_vectored( self: Pin<&mut Self>, cx: &mut Context<'_>, bufs: &[IoSlice<'_>], ) -> Poll<Result<usize, Error>>

Attempt to write bytes from bufs into the object using vectored IO operations.
