Function classific::move_to_cmp_fn

pub fn move_to_cmp_fn<T>(
    comparator: impl Comparator<T>
) -> impl Fn(&T, &T) -> Ordering where
    T: ?Sized, 

This function moves a Comparator into a Fn(&T, &T) -> Ordering to make it usable for APIs which doesn't know about Comparators.

Examples

use std::cmp::Ordering;
use classific::{Comparator, reverse_order, move_to_cmp_fn};

let slice = &mut [1, 2];
slice.sort_by(move_to_cmp_fn(reverse_order()));
assert_eq!(slice, &[2, 1]);
