Available on non-crate feature std only.

Returns the maximum of two values with respect to the specified comparison function.

Returns the second argument if the comparison determines them to be equal.

Examples

use std::cmp;

let result = cmp::max_by(-2, 1, |x: &i32, y: &i32| x.abs().cmp(&y.abs()));
assert_eq!(result, -2);

let result = cmp::max_by(-2, 2, |x: &i32, y: &i32| x.abs().cmp(&y.abs())) ;
assert_eq!(result, 2);
