Struct futures::prelude::stream::TryFlattenUnordered

pub struct TryFlattenUnordered<St>
where
    St: TryStream,
    <St as TryStream>::Ok: TryStream + Unpin,
    <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,
{ /* private fields */ }

Stream for the try_flatten_unordered method.

Implementations

impl<St> TryFlattenUnordered<St>

where St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,

pub fn get_ref(&self) -> &St

Acquires a reference to the underlying sink or stream that this combinator is pulling from.

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

Acquires a mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn get_pin_mut(self: Pin<&mut TryFlattenUnordered<St>>) -> Pin<&mut St>

Acquires a pinned mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn into_inner(self) -> St

Consumes this combinator, returning the underlying sink or stream.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.

Trait Implementations

impl<St> Debug for TryFlattenUnordered<St>

where FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>>: Debug, St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,

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

Formats the value using the given formatter.

impl<St> FusedStream for TryFlattenUnordered<St>

where FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>>: FusedStream, St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<_Item, St> Sink<_Item> for TryFlattenUnordered<St>

where FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>>: Sink<_Item>, St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,

type Error = <FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>> as Sink<_Item>>::Error

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

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

Attempts to prepare the Sink to receive a value.

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

Flush any remaining output from this sink.

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

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

impl<St> Stream for TryFlattenUnordered<St>

where FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>>: Stream, St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,

type Item = <FlattenUnorderedWithFlowController<NestedTryStreamIntoEitherTryStream<St>, PropagateBaseStreamError<St>> as Stream>::Item

Values yielded by the stream.

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

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

Returns the bounds on the remaining length of the stream.

impl<'__pin, St> Unpin for TryFlattenUnordered<St>

where <PinnedFieldsOfHelperStruct<__Origin<'__pin, St>> as PinnedFieldsOfHelperTrait>::Actual: Unpin, St: TryStream, <St as TryStream>::Ok: TryStream + Unpin, <<St as TryStream>::Ok as TryStream>::Error: From<<St as TryStream>::Error>,
