[][src]Struct tokio::prelude::stream::AndThen

#[must_use = "streams do nothing unless polled"]
pub struct AndThen<S, F, U> where
    U: IntoFuture
{ /* fields omitted */ }

A stream combinator which chains a computation onto values produced by a stream.

This structure is produced by the Stream::and_then method.

Methods

impl<S, F, U> AndThen<S, F, U> where
    U: IntoFuture
[src]

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

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

Important traits for &'_ mut W
pub fn get_mut(&mut self) -> &mut S[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.

pub fn into_inner(self) -> S[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.
