[][src]Crate bidirectional_map

A two-way map data structure for cloneable keys and values.

Most functions come in _fwd and _rev variants; where the _fwd variant acts on the second entry given the first, and _rev is the opposite.

This crate is best for values that are cheap to clone, since internally it stores two copies of each element. To use it with large values, consider wrapping them in Rc to make them cheap to clone.
