Extra iterator adaptors, iterator methods and macros.
Documentation
Itertools — extra iterator adaptors, functions and macros. To use the iterator methods in this crate, import the [`Itertools` trait](./trait.Itertools.html): ```ignore use itertools::Itertools; ``` Some iterators or adaptors are used directly like regular structs, for example [`PutBack`](./struct.PutBack.html), [`Unfold`](./struct.Unfold.html), [`Zip`](./struct.Zip.html), [`Stride`](./struct.Stride.html) To enable the macros in this crate, use the `#[macro_use]` attribute: ```ignore #[macro_use] extern crate itertools; ``` ## License Dual-licensed to be compatible with the Rust project.
