    codegen/
        Generated code: This is a Rust crate produced by SCCD compiler (module "sccd.test.cmd.to_rust") from 'common/digitalwatch.xml'. Building it with 'cargo' produces a library.

    wasm/
        Rust crate containing Rust glue code to interact with the generated code in 'codegen' from JavaScript. It should be built with the 'wasm-pack' command, producing JavaScript glue code, and a .wasm-file.
