Support for non-JavaScript WebAssembly

[anderspitman]

I'm implementing a server-side library that I would like to be usable in Go/JavaScript/Rust/Python. I'm investigating whether it would be feasible to use WebAssembly for sharing code between the different language implementations. Part of what the library does is act as an OAuth2 and OIDC client. Currently, oauth2-rs supports reqwest in wasm, but apparently only when using the async http client and compiled with wasm-bindgen. Is that an accurate assessment?

I'm wondering if there's any way to run oauth2-rs in wasm in other languages. I'm guessing with would need to involve WASI or maybe something like extism, but figured I should check here in case I'm missing something.
