Function finite_automata::states_contains_all_from

pub fn states_contains_all_from<'a, S>(
    container: &impl StatesContains<S>, 
    from: &impl StatesSlice<S>, 
    state_indices: impl IntoIterator<Item = StateIndex> + 'a
) -> Option<Box<dyn Iterator<Item = StateIndex> + 'a>>

Convert state indices from from into a set of states and returns the state indices in the container, if all states exist.
