Hey should I be using snapshot testing?
Is `insta` a good lib for that in Rust?

I use it for codespan - seems to work well!

Ooh I could use it for errors messages. I don't even have automated tests for them at the moment

Ohhh, more for just the console dump, I think we need a better solution for codespan
One thing I'd love (but haven't had the time to do) is to have a 'resolved' dignostic representation in codespan that could be independently rendered separated from the file DB. you could then serialise that and make layout-independent assertions on it.

And render a diff of the diagnostics on failure.
Serialising the diagnostics is also kind of important for letting people support accessibility tools, and something we currently do a really bad job of 😰
