Struct relex::Rule[−][src]

pub struct Rule<K: TokenKind> {
    pub kind: K,
    pub re: Regex,
    pub skip: bool,
    pub capture: bool,
}
Expand description

Represents a lexer rule: i.e., a regex that can produce tokens, and whether they are skippable or not. A Rule also stores the token kind.

Fields

kind: Kre: Regexskip: boolcapture: bool

Implementations

impl<K: TokenKind> Rule<K>[src]

pub fn new(kind: K, re: &str) -> Result<Self, Error>[src]

pub fn capture(self, capture: bool) -> Self[src]

set whether tokens generated from this rule should capture groups from the regex

pub fn skip(self, skip: bool) -> Self[src]

set whether this token should be skipped
