Function creusot_contracts::std::cmp::min_by

pub fn min_by<T, F>(v1: T, v2: T, compare: F) -> T
where
    F: FnOnce(&T, &T) -> Ordering,

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

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

Examples

use std::cmp;

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

let result = cmp::min_by(-2, 3, |x: &i32, y: &i32| x.abs().cmp(&y.abs()));
assert_eq!(result, -2);
