Crate array_iterator[][src]

Expand description

This create is now deprecated as this functionality has been implemented in std since 1.15.0. Please use std::array::IntoIter::new instead.

fn pair_iter(a: i32, b: i32) -> impl Iterator<Item=i32> {
	std::array::IntoIter::new([a, b])
}

This crate will continue to receive bug and security fixes for the foreseeable future. No new features, docs or any other changes will be added.

Previous docs are below:


Allows creating owning iterators out of arrays. This is useful for fixed-size iterators. Try writing the following function:

fn pair_iter(a: i32, b: i32) -> impl Iterator<Item=i32> {
	unimplemented!()
}

This is hard to do because most iterators don’t own the values they are iterating over. One ugly solution is:

fn pair_iter(a: i32, b: i32) -> impl Iterator<Item=i32> {
	Some(a).into_iter().chain(Some(b))
}

assert_eq!(pair_iter(1, 2).collect::<Vec<_>>(), &[1, 2]);

This crate allows turning arrays into owning iterators, perfect for short, fixed-size iterators.

use array_iterator::ArrayIterator;

fn pair_iter(a: i32, b: i32) -> impl Iterator<Item=i32> {
	ArrayIterator::new([a, b])
}

assert_eq!(pair_iter(1, 2).collect::<Vec<_>>(), &[1, 2]);
