Bijection

A bijection is a function for which every value in its codomain (set of all possible results) is equivalent to application of the function on a unique value in its domain (all possible inputs). This trait in particular provides an interface for functions that can be 'unapplied' as well as applied. A codec that can convert to and from a set of objects and their serialized form is an example of a bijection.
