I modeled my board & marked numbers independently; the former as a hashmap and the latter as a bit-vector. That simplified my equivalent of is_winner and flag_number: https://github.com/dfontana/adventofcode/blob/master/y2021/src/solutions/day4.rs

Also, instead of summing the remaining values at the end I summed them all at the start then subtracted them as they were checked off, meaning that i didn't need to store a Boolean for each entry recording whether it remained. https://github.com/MichaelCG8/aoc2021/blob/main/src/bin/04.rs

If you're interested comparing solutions, you may check my code here: https://github.com/Killavus/aoc2021/tree/master/day4. It is not optimised for performance though and I propably should've used FromIterator instead of TryFrom from mutable Lines iterator to BingoBoard, but maybe you can take something out of it. Good luck with further AoC challenges!
