Struct roa::stream::AsyncStream

pub struct AsyncStream<IO>(pub IO);

A adaptor between futures::io::{AsyncRead, AsyncWrite} and tokio::io::{AsyncRead, AsyncWrite}.

Trait Implementations

impl<IO> AsyncRead for AsyncStream<IO> where
    IO: Unpin + AsyncRead, 

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<IO> AsyncRead for AsyncStream<IO> where
    IO: Unpin + Read, 

unsafe fn prepare_uninitialized_buffer(
    &self,
    _buf: &mut [MaybeUninit<u8>]
) -> bool

Prepares an uninitialized buffer to be safe to pass to read. Returns true if the supplied buffer was zeroed out.

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

Attempts to read from the AsyncRead into buf.

fn poll_read_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: BufMut, 

Pulls some bytes from this source into the specified BufMut, returning how many bytes were read.

impl<IO> AsyncWrite for AsyncStream<IO> where
    IO: Unpin + AsyncWrite, 

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.

impl<IO> AsyncWrite for AsyncStream<IO> where
    IO: Unpin + Write, 

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<()>>

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

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

Initiates or attempts to shut down this writer, returning success when the I/O connection has completely shut down.

fn poll_write_buf<B>(
    self: Pin<&mut Self>,
    cx: &mut Context,
    buf: &mut B
) -> Poll<Result<usize, Error>> where
    B: Buf, 

Writes a Buf into this value, returning how many bytes were written.
