Struct futures_util::stream::TryFlatten

pub struct TryFlatten<St>where
    St: TryStream,{ /* private fields */ }

Stream for the try_flatten method.

Implementations

impl<St> TryFlatten<St>where
    St: TryStream,
    St::Ok: TryStream,
    <St::Ok as TryStream>::Error: From<St::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 Self>) -> 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> Debug for TryFlatten<St>where
    St: TryStream,
    St::Ok: Debug,

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

Formats the value using the given formatter.

impl<St> FusedStream for TryFlatten<St>where
    St: TryStream + FusedStream,
    St::Ok: TryStream,
    <St::Ok as TryStream>::Error: From<St::Error>,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<St> Stream for TryFlatten<St>where
    St: TryStream,
    St::Ok: TryStream,
    <St::Ok as TryStream>::Error: From<St::Error>,

type Item = Result<<<St as TryStream>::Ok as TryStream>::Ok, <<St as TryStream>::Ok as TryStream>::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.

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

Returns the bounds on the remaining length of the stream.

impl<'__pin, St> Unpin for TryFlatten<St>where
    __Origin<'__pin, St>: Unpin,
    St: TryStream,
