Trait tower::ready_cache::cache::Equivalent
source · [−]pub trait Equivalent<K>where
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 Borrow
solution,
just like HashMap
and BTreeMap
do, so that you can pass &str
to lookup
into a map with String
keys and so on.
Contract
The implementor must hash like K
, if it is hashable.
Required Methods
sourcefn equivalent(&self, key: &K) -> bool
fn equivalent(&self, key: &K) -> bool
Compare self to key
and return true
if they are equal.
