Why does std::io::Read::bytes() iterate over Result<u8, _> instead of just u8? And how to implement a scanner that returns Err immediately on an Err?
I have this question because, as practice, I'm trying to implement a struct Scanner based on this repo, and as an extra, I'd like to be able to handle errors instead of just panicking. However, unlike map(), the skip_while() and take_while() won't handle errors. If the Errs wouldn't happen unless in situations when the program were going very wrong, then I could just panic. Alternatively, is there a way to break and just return an error once bytes() gives an Err, with just iterator function chaining and without having to write loops myself?

What’s everyone working on this week (8/2022)?
This week I read about FnMut and FnOnce. I also found some amazing Rust code for parsing input/output for competitive programming , and solved all the google kickstart problems using it. I made two one hour video of my efforts starting here: https://youtu.be/EvL5YfPw8Ts
