[][src]Struct futures::stream::TakeWhile

#[must_use = "streams do nothing unless polled"]pub struct TakeWhile<St, Fut, F> where
    St: Stream
{ /* fields omitted */ }

Stream for the take_while method.

Implementations

impl<St, Fut, F> TakeWhile<St, Fut, F> where
    F: FnMut(&<St as Stream>::Item) -> Fut,
    Fut: Future<Output = bool>,
    St: Stream
[src]

pub fn get_ref(&self) -> &St[src]

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

pub fn get_mut(&mut self) -> &mut St[src]

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 TakeWhile<St, Fut, F>>) -> Pin<&mut St>[src]

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[src]

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.
