Struct tokio_compat_02::IoCompat

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

IoCompat allows conversion between the 0.2 and 0.3 IO traits.

By wrapping any Tokio IO type in this compatibility wrapper, it becomes usable with the traits of the other version of Tokio.

Trait Implementations

impl<T: AsyncBufRead03> AsyncBufRead for IoCompat<T>

fn poll_fill_buf(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<&[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: AsyncBufRead02> AsyncBufRead for IoCompat<T>

fn poll_fill_buf(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<&[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: AsyncRead03> AsyncRead for IoCompat<T>

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: BufMut>(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>,
    buf: &mut B
) -> Poll<Result<usize>> where
    Self: Sized, 

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

impl<T: AsyncRead02> AsyncRead for IoCompat<T>

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: AsyncWrite03> AsyncWrite for IoCompat<T>

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: AsyncWrite02> AsyncWrite for IoCompat<T>

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.

impl<T: Stream> Stream for IoCompat<T>

type Item = T::Item

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<T::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

impl<'__pin, T> Unpin for IoCompat<T> where
    __Origin<'__pin, T>: Unpin,
