- with two arguments, a mutable collection followed by a closure

slice::sort_unstable_by
to sort
- passes the closure to
Examples
#[macro_use] extern crate colmac; use std::cmp::Ordering::{Equal, Greater, Less}; // sort without a custom closure let mut v1 = vec![2, 4, -1]; sort!(v1); assert_eq!(vec![-1, 2, 4], v1); // sort with; sort in reverse order let mut v2 = vec![2, 4, -1]; sort!(v2, |a, b| match a.cmp(b) { Less => Greater, Greater => Less, Equal => Equal, }); assert_eq!(vec![4, 2, -1], v2);
