Trait binary_heap_plus::Compare

pub trait Compare<T>: Clone {
    fn compare(&mut self, a: &T, b: &T) -> Ordering;
}

Simpler replacement for the Ord trait. The difference is that you can define multiple sort orders on a single type T. Unlike Ord trait, Compare<T> trait can be easily implemented by providing a single function.

Required Methods

fn compare(&mut self, a: &T, b: &T) -> Ordering

Implementors

• impl<T: Ord> Compare<T> for MaxComparator
• impl<T: Ord> Compare<T> for MinComparator
• impl<T, F> Compare<T> for FnComparator<F> where
    F: Clone + FnMut(&T, &T) -> Ordering, 
• impl<K: Ord, T, F> Compare<T> for KeyComparator<F> where
    F: Clone + FnMut(&T) -> K,
