Struct LTS 

Source 
pub struct LTS<S: Clone + Eq + Hash> {
    pub states: HashSet<S>,
    pub initial: S,
    pub transitions: HashMap<S, Vec<(String, S)>>,
}
Expand description

A labeled transition system for refinement checking.

Fields§

§states: HashSet<S>

States.

§initial: S

Initial state.

§transitions: HashMap<S, Vec<(String, S)>>

Transition relation: state → (label, successor state).

Implementations§

Source§

Source

pub fn add_transition(&mut self, from: S, label: impl Into<String>, to: S)

Source

pub fn reachable_states(&self) -> HashSet<S>
