Struct tokio_util::compat::Compat

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

Available on crate feature compat only.

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

Implementations

impl<T> Compat<T>

pub fn get_ref(&self) -> &T

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

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

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

pub fn into_inner(self) -> T

Returns the wrapped item.

Trait Implementations

impl<T: AsRawFd> AsRawFd for Compat<T>

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

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> 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> AsyncRead for Compat<T>

where T: AsyncRead,

fn poll_read( self: Pin<&mut Self>, cx: &mut Context<'_>, slice: &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> AsyncRead for Compat<T>

where T: AsyncRead,

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

Attempts to read from the AsyncRead into buf.

impl<T: AsyncSeek> AsyncSeek for Compat<T>

fn poll_seek( self: Pin<&mut Self>, cx: &mut Context<'_>, pos: SeekFrom ) -> Poll<Result<u64>>

Attempt to seek to an offset, in bytes, in a stream.

impl<T: AsyncSeek> AsyncSeek for Compat<T>

fn start_seek(self: Pin<&mut Self>, pos: SeekFrom) -> Result<()>

Attempts to seek to an offset, in bytes, in a stream.

fn poll_complete( self: Pin<&mut Self>, cx: &mut Context<'_> ) -> Poll<Result<u64>>

Waits for a seek operation to complete.

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<'_>] ) -> Poll<Result<usize, Error>>

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

Like poll_write, except that it writes from a slice of buffers.
