interleave-rs

Interleave is a macro that allows you to create an iterator that interleaves its input iterators.

The reason for making this library is because Itertools only has binary interleaving.

Behaviour

All iterators are exhausted (return None) before the interleaver will return None.

lib.rs:

This crate allows you to create an arbitrary interleaving iterator. Each iterator is guaranteed to be behind the most advanced iterator by at max one next() call. The interleave macro is of arbitrary arity.

#[macro_use]
extern crate interleave;
fn main() {
	use interleave::{IterList, MultiIter};
	let iter = interleave!(1..5, 9..12, -3..2);
	for i in iter {
		println!("{:?}", i);
	}
}

The types returned by the iterator can also be forced:

#[macro_use]
extern crate interleave;
fn main() {
	use interleave::{IterList, MultiIter};
	let iter = interleave!(i8; 1..5, 9..12, -3..2);
	for i in iter {
		println!("{:?}", i);
	}
}

Most information can be found in the examples or the test module.
