Struct tokio_util::compat::Compat

pub struct Compat<T> { /* fields omitted */ }

This is supported on feature="compat" only.

A compatibility layer that allows conversion between the tokio::io and futures-io AsyncRead and AsyncWrite traits.

Methods

impl<T> Compat<T>

pub fn get_ref(&self) -> &T

This is supported on feature="compat" only.

Get a reference to the Future, Stream, AsyncRead, or AsyncWrite object contained within.

pub fn get_mut(&mut self) -> &mut T

This is supported on feature="compat" only.

Get a mutable reference to the Future, Stream, AsyncRead, or AsyncWrite object contained within.

pub fn into_inner(self) -> T

This is supported on feature="compat" only.

Returns the wrapped item.

Trait Implementations

impl<T> AsyncBufRead for Compat<T> where
    T: AsyncBufRead, 

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

Attempts 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<T> AsyncBufRead for Compat<T> where
    T: AsyncBufRead, 

fn poll_fill_buf<'a>(
    self: Pin<&'a mut Self>,
    cx: &mut Context
) -> Poll<Result<&'a [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<T> AsyncRead for Compat<T> where
    T: AsyncRead, 

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

Attempts to read from the AsyncRead into buf.

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_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<T> AsyncRead for Compat<T> where
    T: 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<T> AsyncWrite for Compat<T> where
    T: 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<()>>

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.

impl<T> AsyncWrite for Compat<T> where
    T: 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]
