[−][src]Struct tokio::prelude::stream::TakeWhile
A stream combinator which takes elements from a stream while a predicate holds.
This structure is produced by the Stream::take_while
method.
Methods
impl<S, P, R> TakeWhile<S, P, R> where
R: IntoFuture,
S: Stream,
[src][−]
R: IntoFuture,
S: Stream,
ⓘImportant traits for &'_ mut Rpub fn get_ref(&self) -> &S
[src][−]
ⓘImportant traits for &'_ mut R
Acquires a reference to the underlying stream that this combinator is pulling from.
ⓘImportant traits for &'_ mut Rpub fn get_mut(&mut self) -> &mut S
[src][−]
ⓘImportant traits for &'_ mut R
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.
