Thanks for your great library!

I use both Rust and Haskell, and have learned about error reporting libraries like ariadne and codespan-reporting for a while. Previously when working on a Rust project, I chose codespan-reporting because I preferred its formatting (formatting of ariadne is also beautiful, but a bit too fancy for me), given their interfaces are pretty similar. Is it possible to extend this library to have an alternative codespan-reporting-style formatting for the diagnostic messages? Or is there some design space to expose an API for custom report formatting?

FYI, here is a comparison of the said two styles (BTW it is amusing to see a more Haskell-like syntax for illustration in codespan-reporting the Rust library but a more Rust-like style here):

Name	Illustration
(current) ariadne-style
codespan-reporting-style

If this is deemed non-trivial, I am willing to work on this, in that case would you please provide some guidance?
