Slightly odd suggestion: package it up as both a Python and an NPM module - both just thin wrappers around the combined binary - and then people within those ecosystems will be able to run:

  uvx ut md5 ...

Or:

  npx ut md5 ...

To execute it without having to figure out cargo or how to add a Rust binary to their path.

I've seen a few tools do things like this recently, it's a pretty interesting pattern. I believe there's tooling in the Python/Rust world that makes compiling the different binary wheels relatively easy using GitHub Actions.
