pub trait Equivalent<K: ?Sized> {
    fn equivalent(&self, key: &K) -> bool;
Expand description

Key equivalence trait.

This trait allows hash table lookup to be customized. It has one blanket implementation that uses the regular solution with Borrow and Eq, just like HashMap does, so that you can pass &str to lookup into a map with String keys and so on.


The implementor must hash like K, if it is hashable.

Required Methods

Compare self to key and return true if they are equal.
