## Comparison to thiserror

Use Anyhow if you don't care what error type your functions return, you just
want it to be easy. This is common in application code. Use [thiserror] if you
are a library that wants to design your own dedicated error type(s) so that on
failures the caller gets exactly the information that you choose.
