[−][src]Trait tower::ready_cache::cache::Equivalent
This is supported on crate feature
ready-cache
only.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
pub fn equivalent(&self, key: &K) -> bool
[src]
Compare self to key
and return true
if they are equal.
Implementors
impl<Q, K> Equivalent<K> for Q where
K: Borrow<Q> + ?Sized,
Q: Eq + ?Sized,
[src]
K: Borrow<Q> + ?Sized,
Q: Eq + ?Sized,
