Method dfa

regex/src/compile.rs:105–108

When set, the machine returned is suitable for use in the DFA matching engine. In particular, this ensures that if the regex is not anchored in the beginning, then a preceding `.*?` is included in the program. (The NFA based engines handle the preceding `.*?` explicitly, which is difficult or impossible in the DFA engine.)

(mut self, yes: bool)

    /// based engines handle the preceding `.*?` explicitly, which is difficult
    /// or impossible in the DFA engine.)
    pub fn dfa(mut self, yes: bool) -> Self {
        self.compiled.is_dfa = yes;
        self
    }

    /// When set, the machine returned is suitable for matching text in
    /// reverse. In particular, all concatenations are flipped.
