Overview

Package rust is @lezer/rust's Rust grammar for internal/lezer: its parse tables and styleTags rules, generated from the npm package, and the ports of its external tokenizers (tokens.go). go generate rewrites the tables and the golden files the tests compare against, with LEZER_NODE_MODULES naming a node_modules directory set up as internal/lezer/gen/gen.mjs says, with @lezer/rust@1.0.3 in place of @lezer/java.

Parser is the Rust parser, built the first time it is asked for.
