//! High-performance state machine implementation based on compact `usize` state
//! codes.
//!
//! `FastStateMachine` is designed for hot paths where state and event are
//! represented as dense integer codes and transition lookup must be constant-time.
//! It stores transition rules in a flat table and applies updates with
//! [`qubit_cas::FastCas`].
