Struct futures_util::compat::Compat01As03

#[must_use = "futures do nothing unless you `.await` or poll them"]
pub struct Compat01As03<T> { /* fields omitted */ }

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

Implementations

impl<T> Compat01As03<T>

pub fn new(object: T) -> Self

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

pub fn get_ref(&self) -> &T

Get a reference to 0.1 Future, Stream, AsyncRead, or AsyncWrite object contained within.

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

Get a mutable reference to 0.1 Future, Stream, AsyncRead or AsyncWrite object contained within.

pub fn into_inner(self) -> T

Consume this wrapper to return the underlying 0.1 Future, Stream, AsyncRead, or AsyncWrite object.

Trait Implementations

impl<T: Debug> Debug for Compat01As03<T>

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

Formats the value using the given formatter.

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

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

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: 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.

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

Returns the bounds on the remaining length of the stream.
