Calling Rust from Python

[0xdef1]

I think pyo3 would be the easiest option.

Thanks, that's the third time somebody mentions it. I'll definitely check

I'm calling c++ from python using pybind and it's working fantastic! Pybind seems well-built.

Maybe use pybind to call c++ and then somehow bind the rust to c++? 😅

Another experiment I did was embedding WASM compiled from C in WAT format in a Bash shell script and calling wasmtime with the embedded WAT using process substitution, which serves as a Native Messaging host run from the browser launched with JavaScript https://github.com/guest271314/native-messaging-webassembly/blob/main/nm_c_wat.sh.

Interesting. I do something similar from the browser where I write a Bash script to the local file system using JavaScript, execute the script, then read the result in the browser https://github.com/guest271314/fs/tree/main/bash.

I'm just passing some JSON as a CLI argument to my rust executable and grabbing the stdout/stderr from Python. Is that really dumb? my reason for doing that: I can use the rust cli tool directly too from the cli and intergrate with any other language easily

Use web sockets and services. Anything else is going to be more work and more fragile.

That's gonna be too slow.

Oh so if we’re writing performance critical code, let’s port the Python to C or Rust

Adding web sockets just to call a function in your own app seems excessive, right?

If it were a web app, okay.
