So far I've added code in packages/Python/lldbsuite/test to support Rust
and then I have a simple Rust program that exercises the various
features of the plugin.

The Rust toolchain is very easy to install, so I don't think testing
this in the future should be too difficult.

I am not sure of the details yet, but for expression parsing, I would
like to get the external helper into "rustup" (the Rust toolchain
manager) as well.

What is a good resource for learning about this?
