[−][src]Function out::max_unstable_by
pub fn max_unstable_by<T>(
v: &mut [T],
n: usize,
cmp: impl FnMut(&T, &T) -> Ordering
) -> &mut [T]
Get the n
largest items with a comparator function.
This function is not stable, i.e. it may not preserve the order of equal elements.
This function should be faster than max_by
in most cases.
Panics
Panics if n > len
.
Examples
let mut v = [-5, 4, 1, -3, 2]; let min = out::max_unstable_by(&mut v, 3, |a, b| b.cmp(a)); assert_eq!(min, [1, -3, -5]);
