Struct futures_util::stream::Flatten

pub struct Flatten<St>where
    St: Stream,{ /* private fields */ }

Stream for the flatten method.

Implementations

impl<St> Flatten<St>where St: Stream,

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 for Flatten<St>where Flatten<St, St::Item>: Debug, St: Stream,

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

Formats the value using the given formatter.

impl<St> FusedStream for Flatten<St>where Flatten<St, St::Item>: FusedStream, St: Stream,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<St> Stream for Flatten<St>where Flatten<St, St::Item>: Stream, St: Stream,

type Item = <Flatten<St, <St as Stream>::Item> 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.
