How to organize Rust code for Advent of Code puzzles?
I found this repository which solves the problem by having a src/main.rs file which basically calls cargo run --release {day} and parses the output to extract the time each day took, but I don't find this very satisfactory. I'd prefer to have everything compiled into the same executable, without having to run external commands.

-π- 2021 Day 17 Solutions -π-
Python day 17 solution (GitHub). Not the fewest lines of code, but used dataclasses and modular functions to try improve readability -- I got very confused with keeping track of indices of velocities vs coordinates in other people's posted solutions. I find dataclasses in Python can be a great way to be descriptive about the quantities you are iterating
