Trait Implementations

impl<S, R> AsMut<S> for Extending<S, R>

fn as_mut(&mut self) -> &mut S

Converts this type into a mutable reference of the (usually inferred) input type.

impl<S, R> AsRef<S> for Extending<S, R>

fn as_ref(&self) -> &S

Converts this type into a shared reference of the (usually inferred) input type.

impl<S: Debug, R: Debug> Debug for Extending<S, R>

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

Formats the value using the given formatter.

impl<S: Default, R: Default + Stream> Default for Extending<S, R>

fn default() -> Self

Returns the “default value” for a type.

impl<Route, Msg, S: FlushRoute<Route, Msg>, R> FlushRoute<Route, Msg> for Extending<S, R>

Available on crate feature route-sink only.

fn poll_flush_route( self: Pin<&mut Self>, route: &Route, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

fn poll_close_route( self: Pin<&mut Self>, route: &Route, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

impl<S: Default, R: Stream> From<R> for Extending<S, R>

fn from(incoming: R) -> Self

Converts to this type from the input type.

impl<A, S: FusedStream + ExtendPinned<A>, R: Stream<Item = A>> FusedStream for Extending<S, R>

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<Route, Msg, S: ReadyRoute<Route, Msg>, R> ReadyRoute<Route, Msg> for Extending<S, R>

Available on crate feature route-sink only.

fn poll_ready_route( self: Pin<&mut Self>, route: &Route, cx: &mut Context<'_>, ) -> Poll<Result<(), Self::Error>>

impl<Route, Msg, S: ReadySome<Route, Msg>, R> ReadySome<Route, Msg> for Extending<S, R>

Available on crate feature route-sink only.

fn poll_ready_some( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Result<Route, Self::Error>>

impl<Item, S: Sink<Item>, R> Sink<Item> for Extending<S, R>

Available on crate feature sink only.

type Error = <S as Sink<Item>>::Error

The type of value produced by the sink when an error occurs.

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

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Item) -> Result<(), Self::Error>

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

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

Flush any remaining output from this sink.

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

Flush any remaining output and close this sink, if necessary.

impl<A, S: Stream + ExtendPinned<A>, R: Stream<Item = A>> Stream for Extending<S, R>

type Item = <S as Stream>::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.

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

Returns the bounds on the remaining length of the stream.
