Utility for finding the minimum and maximum elements of an iterable collection in a single pass without copy. Similar to C++'s minmax_element, Julia's extrema and Ruby's minmax.

Usage

Just call it on a collection!

let xs = vec![0, 1, 2, 3];
let minmax = xs.extrema();

assert_eq!(minmax, Some((0, 3)));

Utility for finding the minimum and maximum values of a collection. Similar to C++'s minmax_element, Julia's extrema and Ruby's minmax.

Quick Start:

Just call it on any iterable collection!

let my_set: HashSet<i32> = (1..300).collect();
let (min, max) = my_set.iter().extrema().unwrap();

assert_eq!((min, max), (&1, &300));
