Crate hashable[−][src]

This library provides HashMap and HashSet replacements that implement the Hash trait -- HashableHashMap and HashableHashSet.

Example

The following is rejected by the compiler:

let mut inner_set = std::collections::HashSet::new();
inner_set.insert("inner value");

let mut outer_set = std::collections::HashSet::new();
outer_set.insert(inner_set);

error[E0277]: the trait bound `HashSet<&str>: Hash` is not satisfied

The error can be resolved by swapping the inner HashSet with HashableHashSet:

let mut inner_set = hashable::HashableHashSet::new();
inner_set.insert("inner value");

let mut outer_set = std::collections::HashSet::new();
outer_set.insert(inner_set);

Structs

HashableHashMap	A `HashMap` wrapper that implements `Hash` by sorting pre-hashed entries and feeding those back into the passed-in `Hasher`.
HashableHashSet	A `HashSet` wrapper that implements `Hash` by sorting pre-hashed entries and feeding those back into the passed-in `Hasher`.
