[−][src]Struct tokio::prelude::stream::Chunks
An adaptor that chunks up elements in a vector.
This adaptor will buffer up a list of items in the stream and pass on the
vector used for buffering when a specified capacity has been reached. This
is created by the Stream::chunks
method.
Methods
impl<S> Chunks<S> where
S: Stream,
[src]
S: Stream,
ⓘImportant traits for &'_ mut Wpub fn get_ref(&self) -> &S
[src]
Acquires a reference to the underlying stream that this combinator is pulling from.
ⓘImportant traits for &'_ mut Wpub 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.
