Struct ConnStream 

pub struct ConnStream { /* private fields */ }

Wraps a ConnCtx and implements futures_io::{AsyncRead, AsyncWrite, AsyncBufRead}. Wraps a ConnCtx and implements AsyncRead, AsyncWrite, and AsyncBufRead.

Created via ConnStream::new. The inner ConnCtx is still accessible via conn_ctx for operations that have no trait equivalent (e.g. connect, shutdown_write).

Copy profile

Trait method	Copies (recv)	Mechanism
AsyncRead::poll_read	1	accumulator → caller buf
AsyncBufRead::poll_fill_buf	0	refcounted Bytes slice
AsyncWrite::poll_write	1	caller buf → send pool

Implementations

impl ConnStream

pub fn new(ctx: ConnCtx) -> Self

Wrap a ConnCtx in a streaming adapter.

pub fn conn_ctx(&self) -> ConnCtx

Borrow the inner ConnCtx.

Useful for operations without a trait equivalent, such as ConnCtx::connect or ConnCtx::peer_addr.

Trait Implementations

impl AsyncBufRead for ConnStream

fn poll_fill_buf( self: Pin<&mut Self>, _cx: &mut Context<'_>, ) -> Poll<Result<&[u8]>>

Attempt to return the contents of the internal buffer, filling it with more data from the inner reader if it is empty.

fn consume(self: Pin<&mut Self>, amt: usize)

Tells this buffer that amt bytes have been consumed from the buffer, so they should no longer be returned in calls to poll_read.

impl AsyncRead for ConnStream

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 ConnStream

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.
