Struct cosmic::iced_futures::futures::prelude::future::TryFlattenStream

pub struct TryFlattenStream<Fut>
where
    Fut: TryFuture,
{ /* private fields */ }

Future for the try_flatten_stream method.

Trait Implementations

impl<Fut> Debug for TryFlattenStream<Fut>

where TryFlatten<Fut, <Fut as TryFuture>::Ok>: Debug, Fut: TryFuture,

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

Formats the value using the given formatter.

impl<Fut> FusedStream for TryFlattenStream<Fut>

where TryFlatten<Fut, <Fut as TryFuture>::Ok>: FusedStream, Fut: TryFuture,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<_Item, Fut> Sink<_Item> for TryFlattenStream<Fut>

where TryFlatten<Fut, <Fut as TryFuture>::Ok>: Sink<_Item>, Fut: TryFuture,

type Error = <TryFlatten<Fut, <Fut as TryFuture>::Ok> as Sink<_Item>>::Error

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

fn poll_ready( self: Pin<&mut TryFlattenStream<Fut>>, cx: &mut Context<'_>, ) -> Poll<Result<(), <TryFlattenStream<Fut> as Sink<_Item>>::Error>>

Attempts to prepare the Sink to receive a value.

fn start_send( self: Pin<&mut TryFlattenStream<Fut>>, item: _Item, ) -> Result<(), <TryFlattenStream<Fut> as Sink<_Item>>::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 TryFlattenStream<Fut>>, cx: &mut Context<'_>, ) -> Poll<Result<(), <TryFlattenStream<Fut> as Sink<_Item>>::Error>>

Flush any remaining output from this sink.

fn poll_close( self: Pin<&mut TryFlattenStream<Fut>>, cx: &mut Context<'_>, ) -> Poll<Result<(), <TryFlattenStream<Fut> as Sink<_Item>>::Error>>

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

impl<Fut> Stream for TryFlattenStream<Fut>

where TryFlatten<Fut, <Fut as TryFuture>::Ok>: Stream, Fut: TryFuture,

type Item = <TryFlatten<Fut, <Fut as TryFuture>::Ok> as Stream>::Item

Values yielded by the stream.

fn poll_next( self: Pin<&mut TryFlattenStream<Fut>>, cx: &mut Context<'_>, ) -> Poll<Option<<TryFlattenStream<Fut> 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.

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

Returns the bounds on the remaining length of the stream.

impl<'__pin, Fut> Unpin for TryFlattenStream<Fut>

where <PinnedFieldsOfHelperStruct<__Origin<'__pin, Fut>> as PinnedFieldsOfHelperTrait>::Actual: Unpin, Fut: TryFuture,
