Struct iter_chunks::Chunks

pub struct Chunks<I: Iterator> { /* private fields */ }

An iterator-like struct that yields chunks.

This struct is created by chunks method on IterChunks. See its documentation for more.

Implementations

impl<I: Iterator> Chunks<I>

pub fn next(&mut self) -> Option<Chunk<'_, I>>

Similar to Iterator::next, but not implements Iterator due to lifetime.

The underlying iterator implementations may choose to resume iteration after finished, so calling Chunks::next may also return Some(Chunk) after returning None.

pub fn for_each(&mut self, f: impl FnMut(Chunk<'_, I>))

Similar to Iterator::for_each.

use iter_chunks::IterChunks;

let arr = [1, 4, 2, 3, 5];
arr.into_iter().chunks(2).for_each(|chunk| {
    assert_eq!(chunk.sum::<i32>(), 5);
});
