Struct ScanMatch 

pub struct ScanMatch {
    pub rank: usize,
    pub token_id: TokenId,
    pub len_bytes: usize,
}

A match starting exactly at the scan position.

Fields

rank: usize

Index into the ranked spec list (smaller = higher rank).

token_id: TokenId

len_bytes: usize

Match length in bytes from the scan position (the caller’s line tracker converts to code points when it feeds the matched slice). Can be 0 for a nullable spec (e.g. a* at a non-matching position) — Scanner does not reject nullable patterns; the front-ends (basic lexer, dynamic Earley) reject zero-width TERMINALS at grammar-build time, so a real parse never lexes a zero-width match.
