Struct futures_test::future::InterleavePending

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

Wrapper that interleaves Poll::Pending in calls to poll.

See the interleave_pending methods on:

• FutureTestExt
• StreamTestExt
• AsyncReadTestExt
• AsyncWriteTestExt

Methods

impl<T> InterleavePending<T>

pub fn get_ref(&self) -> &T

Acquires a reference to the underlying I/O object that this adaptor is wrapping.

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

Acquires a mutable reference to the underlying I/O object that this adaptor is wrapping.

pub fn get_pin_mut<'a>(self: Pin<&'a mut Self>) -> Pin<&'a mut T>

Acquires a pinned mutable reference to the underlying I/O object that this adaptor is wrapping.

pub fn into_inner(self) -> T

Consumes this adaptor returning the underlying I/O object.

Trait Implementations

impl<T: Unpin> Unpin for InterleavePending<T>

impl<T: Debug> Debug for InterleavePending<T>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<Fut: Future> Future for InterleavePending<Fut>

type Output = Fut::Output

The type of value produced on completion.

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

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

impl<St: Stream> Stream for InterleavePending<St>

type Item = St::Item

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: AsyncRead> AsyncRead for InterleavePending<R>

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

Attempt to read from the AsyncRead into buf.

unsafe fn initializer(&self) -> Initializer

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

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<W: AsyncWrite> AsyncWrite for InterleavePending<W>

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<R: AsyncBufRead> AsyncBufRead for InterleavePending<R>

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>, amount: 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].
