[C++20] ClearIO library (unfinished)
Yeah, but parsing format strings in runtime induces an overhead, and doing it in compile time is not trivial, and I’m not sure ClearIO is worth the trouble, since it turns out scnlib exists.

My AoC2021 solutions in C++
The code is rather nice (in my biased opinion) and makes heavy use of a couple of libraries like scnlib and [Eigen](eigen.tuxfamily.org/). Some things could probably be more optimized but I mainly focused on conciseness. I hope this is useful and I can explain my thought process further if you have any questions.

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.
