It's one character in the best case. In the worse case you need to convert the error types to your error type which just re-wraps or replicates the upstream error type. Then repeat this for every library type you use. Zigs error design seems saner in this aspect at least. Rust, IMHO, just makes errors require lots of unnecessary manual labor instead of being smart about it.

Alternatively everything just gets put into a `dyn trait` and you're effectively just bubbling up errors just like with exceptions, but with way more programmer overhead. The performance overhead of constantly doing if/else branches for errors adds up as well in some situations.

Of course a fair bit of Rust code just uses `unwrap` to deal with inconvenient errors.
