//! Concrete reference automata implementations.

//! The types in this module are intentionally small and explicit:
//! - [`SimpleDFA`](dfa::SimpleDFA): deterministic transition table with
//! `State × Input -> Option<State>`.
//! - [`SimpleNFA`](nfa::SimpleNFA): nondeterministic transition relation with
//! `State × Input -> set of states`.
