Took me a while to figure out how to debug a hanging Rust test. The best invocation seems to be:
$ RUST_TEST_THREADS=1 cargo test -- --nocapture
This will print test names before execution, so you can see where you're hanging. --nocapture lets you see print output immediately.

"After I linked difftastic, one of my friends immediately used difftastic to find a stealthy bug, five stars!"
I'm still trying to find a sweet spot between 'show the general syntax' and 'show a concrete example' in the CLI docs for difftastic.

I'm currently showing the syntax, immediately followed by an example. What do you think?
