Advent of Code 2023 is nigh
I ended up using parser combinator library nom. It's not something I use daily, therefore parsing became a puzzle on its own.
Nom already has a parser for numbers. However, I didn't find an elegant way to take at most one digit. In the end I used take_while_m_n, and mapped it with u64::from_str().
Another challenge was absence of something such as find_all, that would repeatedly try to parse beginning from each character and then return all matches. I ended up writing my own combinator.

Advent of Code 2023 is nigh
Ah, that's a nice observation about zero, that would have saved me some typing. :-)
I did the same thing with my actual solution in terms of order (but I went 0, 1, 2, 3), but mostly so I could truncate the matching array to solve part 1. Notably, that was a ret-con of my actual solution to part 1, which I originally did by just mapping the characters through .is_ascii_digit(), but I wanted to consolidate the code a little. I ended up with:
