Module cmp_wrap::permissive

The permissive option will let you compare different types as long as they are mapped (keyed) to comparable Key types.

Be careful as you may compare things you didn't want to compare.

Example

The permissive option will let you compare different types or by different keys, as long as they are comparable.

use cmp_wrap::permissive::KeyCmpContext;

let long_vec = vec![1,2,3,4,5];
let short_vec = vec![4,2];

let by_length = KeyCmpContext::new(|v: &&Vec<_>| v.len());
let by_first_element = KeyCmpContext::new(|v: &&Vec<_>| v[0]);

let by_length_long = by_length.wrap(&long_vec);

let by_first_element_short = by_first_element.wrap(&short_vec);

assert!(by_length_long > by_first_element_short,
        "The long array is longer then the first element of the sort array")

Structs

CmpByKey	The main structure of this crate. Lets you define a "key function" over any structure, which will change the way the value is being compared. Very useful when you need to enter your data to different data structures (such as max heaps, sorted trees and so on), with different comparision criteria.
KeyCmpContext	Used to easily wrap multiple values with the same key function.
