A SourceCode is anything that implements the SourceCode trait. If you want to work off a file more dynamically, you'll need to write an implementation for it. All you need to be able to do is tell miette how to read a specific span from it: https://github.com/zkat/miette/blob/main/src/protocol.rs#L211-L231

I always thought that miette was a crate like coloreyre. Later I figured out that miette is suitable for some lexical analysis or as a language interpreter. I'm not sure. I always want to let miette capture the context part of the current rs code to use in some fancy output can be displayed when panic, this is probably some misunderstanding of mine
