Crate collected[−][src]
Expand description
Collection types that takes the maximum, the summation and more from iterators.
Every collection type in the crate implements FromIterator
,
Extend
and Default
traits. They can be built from
collect()
, and can be updated by extend()
.
For example, it makes it easy to compute maximum and minimum value from an iterator
using unzip()
in single step.
use collected::{MaxVal, MinVal};
let (min, max): (MinVal<_>, MaxVal<_>) = vec![3, 1, 5, 2, 4, 3, 6]
.into_iter()
.map(|val| (val, val))
.unzip();
assert_eq!(min.unwrap(), 1);
assert_eq!(max.unwrap(), 6);
