 I started doing a copy of my original "naive" algorithm, and as it was too slow, I decided to learn [how to pass closures in Rust](https://doc.rust-lang.org/book/ch13-01-closures.html).

+This one was already complicated in Ruby, but it gets even worse when you have to deal with [Rust's lifetimes](https://doc.rust-lang.org/rust-by-example/scope/lifetime.html). The concept in itself is kinda okay to understand, but the way it has to be used sometimes makes no sense. I guess I'll get used to it with time. A [nice crate](https://docs.rs/advent-of-code/2022.0.66/src/advent_of_code/year2015/day07.rs.html) helped me see through it a bit more clearly.
