I don't think you installed nightly toolchain correctly. ```bash rustup toolchain install nightly rustup target add --toolchain nightly wasm32-unknown-emscripten ``` If it still errors, try maturin git version: ```bash cargo...

You needed to install emscripten since we are doing out of tree build for pyodide.

Opened https://github.com/huggingface/tokenizers/pull/1021 to ease the process.

I've released maturin [v0.13.0-beta.8](https://github.com/PyO3/maturin/releases/tag/v0.13.0-beta.8) so you should be able to use `sudo pip install maturin==0.13.0b8` instead of `cargo install` now.

Here is how [napi-rs](https://github.com/napi-rs/napi-rs) does typescript `.d.ts` file generation for inspiration: https://github.com/napi-rs/napi-rs/pull/696/commits/741dd93aff5a50954fca45ba3c6a84a6d562fc8f

https://github.com/changesets/changesets but in TypeScript, there is [a similar project in Rust](https://github.com/DmitryDodzin/mol) but it doesn't seem mature enough.

Hitting #1088 when I'm trying to expose [crfs::Model](https://docs.rs/crfs/0.1.3/crfs/struct.Model.html) which has a lifetime parameter to Python. It would be great if this code works when `data` is a Python managed buffer....
