pub struct HashableInPredicate<T>
where T: Hash + Eq + Debug,
{ /* private fields */ }
Expand description

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.
