itertools 0.10.1

Extra iterator adaptors, functions and macros.

To extend [Iterator] with methods in this crate, import the [Itertools] trait:

use itertools::Itertools;

Now, new methods like interleave are available on all iterators:

use itertools::Itertools;

let it = (1..3).interleave(vec![-1, -2]);
itertools::assert_equal(it, vec![1, -1, 2, -2]);

Most iterator methods are also provided as functions (with the benefit that they convert parameters using [IntoIterator]):

use itertools::interleave;

for elt in interleave(&[1, 2, 3], &[2, 3, 4]) {
/* loop body */
}

Crate Features

• use_std
• Enabled by default.
• Disable to compile itertools using #![no_std]. This disables any items that depend on collections (like group_by, unique, kmerge, join and many more).
