[−][src]Trait automata::Alphabet
A generic alphabet.
Eq
, Ord
, and Hash
are assumed to be provided for the finite set to
simplify data structures by allowing use of different map and set types.
An interesting case may be using Option<A> where A: Alphabet
which
provides the possibility to consider an 'anything else' case and an actually
infinte alphabet of which the automaton just uses a finite set.
