10//! Collection types that takes the maximum, the summation and more from iterators.
11//!
12//! Every collection type in the crate implements [`FromIterator`](core::iter::FromIterator),
13//! [`Extend`](core::iter::Extend) and [`Default`](Default) traits. They can be built from
14//! [`collect()`](Iterator::collect), and can be updated by [`extend()`](Extend::extend).
15//!
16//! For example, it makes it easy to compute maximum and minimum value from an iterator
17//! using [`unzip()`](Iterator::unzip) in single step.
18//!
19//! ```rust
20//! use collected::{MaxVal, MinVal};
21//! let (min, max): (MinVal<_>, MaxVal<_>) = vec![3, 1, 5, 2, 4, 3, 6]
22//!     .into_iter()
23//!     .map(|val| (val, val))
24//!     .unzip();
25//! assert_eq!(min.unwrap(), 1);
26//! assert_eq!(max.unwrap(), 6);
27//! ```
