Rust-fsm is finite state machine implementation in Rust. It exposes specific macros to make it fairly expressive to work with. Currently, Scala-like syntax is an inspiration for this library. You can get pretty far with macros, except Rust is currently limited in mutli-statement macros.

extern mod fsm;
use fsm;
fn main() {
// Create a new set of states.
// `State` defines a new module where each state is defined in.
defstates! (State -> Unlocked, Locked);
// Create a new FSM and pass an initial state:
let mut machine = fsm::StateMachine::new(State::Unlocked);
// Do something when we lock the machine:
machine.when(State::Locked, || {
println!("We have locked it again.");
});
machine.switch(State::Locked);
