I agree, I think the Rust Gods should think of some ingenious way (which actually seems to be the norm when it comes to the "thoughtfulness" of the Rust ecosystem) to do both library-style error handling (where specific error conditions have to be handled differently by a library consumer) as well as app-style error handling (where multiple error conditions can be handled pretty much the same way by an event loop), add it to the standard library and `clippy` out (lint) the livin' lights out of every other approach out there :).
