Struct AndThen
#[must_use = "streams do nothing unless polled"]
pub struct AndThen<St, Fut, F> { /* private fields */ }Stream for the and_then method.
Implementations
impl<St, Fut, F> AndThen<St, Fut, F>
where
St: TryStream,
F: FnMut(St::Ok) -> Fut,
Fut: TryFuture<Error = St::Error>,
fn get_ref(&self) -> &StAcquires a reference to the underlying sink or stream that this combinator is pulling from.
fn get_mut(&mut self) -> &mut StAcquires 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.
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.
fn into_inner(self) -> StConsumes 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.
