@cascade-code/language-rust

First-party structured Rust analysis for modules, use, crate/include forms, symbols, and Cargo package/workspace evidence.

Installation and use

Normal CLI users should not install it directly; the CLI loads it automatically for .rs files and Cargo metadata. Custom integrations can instantiate it:

npm install @cascade-code/language-rust@next

import { createRustPlugin } from "@cascade-code/language-rust";
const plugin = createRustPlugin();

Exports include RustLanguagePlugin, createRustPlugin, and extractRustDependencies. Its documented capability level is Structured, with file, module, symbol, build, and runtime-dynamic dependency evidence.

Environment, security, and limitations

Requires Node.js 22.13 or newer and does not invoke Cargo, rustc, procedural macros, or build scripts. cfg selection, macro expansion, generated sources, target selection, and non-literal include paths can change the compiled graph.
