pub struct Chunks<St: Stream> { /* fields omitted */ }

[−] Expand description

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.

Important traits for &'a mut R

impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;

pub fn get_ref(&self) -> &St

[−]

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

Important traits for &'a mut R

pub fn get_mut(&mut self) -> &mut St

[−]

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) -> St

[−]

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.

fn fmt(&self, f: &mut Formatter) -> Result

[−]

Formats the value using the given formatter.

impl<St: Unpin + Stream> Unpin for Chunks<St>

impl<St: Stream> Stream for Chunks<St>

[+]

type Item = Vec<St::Item>

Values yielded by the stream.

fn poll_next(self: PinMut<Self>, cx: &mut Context) -> Poll<Option<Self::Item>>

[−]

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.
