   @rj-atw you can start here https://github.com/apache/arrow/blob/master/docs/source/developers/docker.rst
   
   I assume you'll need to adjust the [rust_build.sh](https://github.com/apache/arrow/blob/master/ci/scripts/rust_build.sh) script to accept either a target arch environment variable (preferable) or a CLI argument than add a new docker-compose entry (like debian-rust-wasm32) similar to [debian-rust](https://github.com/apache/arrow/blob/master/docker-compose.yml#L928) where you pass the wasm variable.
   
   Once that works with `archery docker run debian-rust-wasm32` you can add a matrix entry to execute debian-rust-wasm32 in the [rust github actions configuration](https://github.com/apache/arrow/blob/master/.github/workflows/rust.yml#L52).
