Hi all,

I'm looking into the Rust shim PRs (great job!) and I'd like to be able
reasonably easily to run the binary standalone, preferrably under
debugger, mostly to verify my assumptions.

I noticed the binary is somewhat hard to run though - it has complex
interactions with its environment and makes quite a lot of assumptions
about it.  I was wondering if there's a way to mock these, or how shim
developers go about debugging and verifying the code.

Thanks in advance!
