[][src]Struct futures::stream::Then

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

Stream for the then method.

Methods

impl<St, Fut, F> Then<St, Fut, F> where
    F: FnMut(<St as Stream>::Item) -> Fut,
    St: Stream
[src]

Important traits for &'_ mut F
pub fn get_ref(&self) -> &St[src]

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

Important traits for &'_ mut F
pub fn get_mut(&mut self) -> &mut St[src]

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

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

Important traits for Pin<P>
pub fn get_pin_mut(self: Pin<&mut Then<St, Fut, F>>) -> Pin<&mut St>[src]

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

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

pub fn into_inner(self) -> St[src]

Consumes this combinator, returning the underlying stream.

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