impl<Fut: Future01> Future for Compat01As03<Fut>

type Output = Result<Fut::Item, Fut::Error>

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

The type of value produced on completion.

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

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<St: Stream01> Stream for Compat01As03<St>

type Item = Result<St::Item, St::Error>

Values yielded by the stream.

fn poll_next(self: Pin<&mut Self>, cx: &mut Context) -> Poll<Option<Self::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.

impl<R: AsyncRead01> AsyncRead for Compat01As03<R>

unsafe fn initializer(&self) -> Initializer

Determines if this AsyncReader can work with buffers of uninitialized memory.

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

Attempt to read from the AsyncRead into buf.

default fn poll_vectored_read(
    self: Pin<&mut Self>,
    cx: &mut Context,
    vec: &mut [&mut IoVec]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into vec using vectored IO operations.

impl<W: AsyncWrite01> AsyncWrite for Compat01As03<W>

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

Attempt to write bytes from buf into the object.

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

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<(), Error>>

Attempt to close the object.

default fn poll_vectored_write(
    self: Pin<&mut Self>,
    cx: &mut Context,
    vec: &[&IoVec]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from vec into the object using vectored IO operations.
