[−][src]Struct futures::stream::Chunks
#[must_use = "streams do nothing unless polled"]pub struct Chunks<St> where
St: Stream, { /* fields omitted */ }
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.

impl<St> Chunks<St> where
St: Stream + Stream, ⓘImportant traits for &'a mut Ipub fn get_ref(&self) -> &St[src]
pub fn get_ref(&self) -> &StAcquires a reference to the underlying stream that this combinator is pulling from.
ⓘImportant traits for &'a mut Ipub fn get_mut(&mut self) -> &mut St[src]
pub fn get_mut(&mut self) -> &mut StAcquires 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) -> St[src]
pub fn into_inner(self) -> StConsumes 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.
