Trait Equivalent

pub trait Equivalent<Q>
where
    Q: ?Sized,
{
    // Required method
    fn equivalent(&self, key: &Q) -> bool;
}

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.

Contract

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

Required Methods

fn equivalent(&self, key: &Q) -> bool

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