PyO3 for Deno/V8/FFI?

[ancoron]

In the Python ecosystem, the PyO3 project has been a game changer by allowing developers to seamlessly interact with complex data structures between the Python runtime and Rust.

This opened the door for popular libraries that can bring a lot of optimizations into the Python ecosystem.

In order to provide a similar experience in the JavaScript world, libraries like Polars use the NAPI wrapper napi-rs.

Since current FFI does not support passing complex data types "as-is" without a client-side serialize/deserialize code, I was thinking a helper library should already exist, but couldn't find anything.

Is someone aware of anything like that that we can use with Deno?
