Enum heim_common::prelude::futures::future::Either

pub enum Either<A, B> {
    Left(A),
    Right(B),
}

Combines two different futures, streams, or sinks having the same associated types into a single type.

Variants

Left(A)

First branch of the type

Right(B)

Second branch of the type

Implementations

impl<A, B, T> Either<(T, A), (T, B)>

pub fn factor_first(self) -> (T, Either<A, B>)

Factor out a homogeneous type from an either of pairs.

Here, the homogeneous type is the first element of the pairs.

impl<A, B, T> Either<(A, T), (B, T)>

pub fn factor_second(self) -> (Either<A, B>, T)

Factor out a homogeneous type from an either of pairs.

Here, the homogeneous type is the second element of the pairs.

impl<T> Either<T, T>

pub fn into_inner(self) -> T

Extract the value of an either over two equivalent types.

Trait Implementations

impl<A, B> Clone for Either<A, B> where
    A: Clone,
    B: Clone, 

pub fn clone(&self) -> Either<A, B>

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<A, B> Debug for Either<A, B> where
    A: Debug,
    B: Debug, 

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

Formats the value using the given formatter.

impl<A, B> FusedFuture for Either<A, B> where
    A: FusedFuture,
    B: FusedFuture<Output = <A as Future>::Output>, 

pub fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<A, B> FusedStream for Either<A, B> where
    A: FusedStream,
    B: FusedStream<Item = <A as Stream>::Item>, 

pub fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<A, B> Future for Either<A, B> where
    A: Future,
    B: Future<Output = <A as Future>::Output>, 

type Output = <A as Future>::Output

The type of value produced on completion.

pub fn poll(
    self: Pin<&mut Either<A, B>>,
    cx: &mut Context<'_>
) -> Poll<<Either<A, B> as Future>::Output>

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

impl<A, B> Stream for Either<A, B> where
    A: Stream,
    B: Stream<Item = <A as Stream>::Item>, 

type Item = <A as Stream>::Item

Values yielded by the stream.

pub fn poll_next(
    self: Pin<&mut Either<A, B>>,
    cx: &mut Context<'_>
) -> Poll<Option<<Either<A, B> 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.

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

Returns the bounds on the remaining length of the stream.

impl<'pin, A, B> Unpin for Either<A, B> where
    __Either<'pin, A, B>: Unpin,
