Struct predicates::iter::HashableInPredicate [−][src]
Predicate that returns true
if variable
is a member of the pre-defined
HashSet
, otherwise returns false
.
Note that this implementation requires Item
to be Hash + Eq
. The
InPredicate
uses a less efficient search algorithm but only
requires Item
implement PartialEq
. The implementation-specific
predicates will be deprecated when Rust supports trait specialization.
This is created by the predicate::in_hash
function.
