Struct regex_automata::util::determinize::state::StateBuilderNFA

pub(crate) struct StateBuilderNFA {
    repr: Vec<u8>,
    prev_nfa_state_id: StateID,
}

A state builder that collects some assertions and NFA state IDs.

When collecting NFA state IDs is finished, this can be used to build a State if necessary.

When dont with building a state (regardless of whether it got kept or not), it’s usually a good idea to call clear to get an empty builder back so that it can be reused to build the next state.

Fields

repr: Vec<u8>

prev_nfa_state_id: StateID
