Struct futures::compat::Compat01As03

#[must_use = "futures do nothing unless polled"]
pub struct Compat01As03<T> { /* fields omitted */ }

Converts a futures 0.1 Future, Stream, AsyncRead, or AsyncWrite object to a futures 0.3-compatible version,

Methods

impl<T> Compat01As03<T>

pub fn new(object: T) -> Compat01As03<T>

Wraps a futures 0.1 Future, Stream, AsyncRead, or AsyncWrite object in a futures 0.3-compatible wrapper.

Trait Implementations

impl<W> AsyncWrite for Compat01As03<W> where
    W: AsyncWrite, 

fn poll_write(
    &mut self,
    waker: &Waker,
    buf: &[u8]
) -> Poll<Result<usize, Error>>

Attempt to write bytes from buf into the object.

fn poll_flush(&mut self, waker: &Waker) -> Poll<Result<(), Error>>

Attempt to flush the object, ensuring that any buffered data reach their destination.

fn poll_close(&mut self, waker: &Waker) -> Poll<Result<(), Error>>

Attempt to close the object.

fn poll_vectored_write(
    &mut self,
    waker: &Waker,
    vec: &[&IoVec]
) -> Poll<Result<usize, Error>>

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

impl<T> Unpin for Compat01As03<T>

impl<Fut> Future for Compat01As03<Fut> where
    Fut: Future, 

type Output = Result<<Fut as Future>::Item, <Fut as Future>::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 Compat01As03<Fut>>,
    waker: &Waker
) -> Poll<<Compat01As03<Fut> as Future>::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<T> Debug for Compat01As03<T> where
    T: Debug, 

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

Formats the value using the given formatter.

impl<St> Stream for Compat01As03<St> where
    St: Stream, 

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

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Compat01As03<St>>,
    waker: &Waker
) -> Poll<Option<<Compat01As03<St> as Stream>::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 for Compat01As03<R> where
    R: AsyncRead, 

unsafe fn initializer(&self) -> Initializer

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

fn poll_read(
    &mut self,
    waker: &Waker,
    buf: &mut [u8]
) -> Poll<Result<usize, Error>>

Attempt to read from the AsyncRead into buf.

fn poll_vectored_read(
    &mut self,
    waker: &Waker,
    vec: &mut [&mut IoVec]
) -> Poll<Result<usize, Error>>

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