My Advent of Code 2020 solutions in the Rust programming language. This repository holds a separate Rust project for each day and part.

This year I attempt to develop a short, compact and fast solution for each problem.

Here is how long each solution takes to run to completion. All solutions are measured (non scientifically) with hyperfine on a i5-4670k @ 3.8Ghz machine running Linux. Timings include binary execution, input reading and result printing delays.

Each Rust project contains a input.txt file, holding the puzzle input. Simply run the project to see the solution appear.

# Switch to day 1a, and run it
cd day01a
cargo run --release

Some solutions might require Rust Nightly.
