My solutions for Advent of Code 2020 in Rust.

⚠️ My input files are not committed as per request of the Advent of Code author.

1. Make sure Rust is installed on the system.
2. Add the input in a file named input.txt next to the solution before running.
3. Run: cargo run --bin {day}

Rust is blazingly fast, but cargo run builds and runs an unoptimized version to improve compile times at the expense of runtime speed. To achieve ludicrous speed:

Run a release build:

cargo build -r

Then:

./target/release/{day}

Enjoy!
