Advent of Code 2021
Giving Advent of Code 2021 🎄 a go to with Rust 🦀.
Cargo
Cargo is Rust’s build system and package manager.
Building and Running a Cargo Project
Run cargo build to compile the project.
The executable will be created in target/debug/advent-of-code-2021.
To compile and execute simply run cargo run.
Building for Release
Run cargo build --release to compile the project with optimizations.
The executable will be created in target/release/advent-of-code-2021.
Continuous integration
The CI uses Github Actions and runs 4 jobs:
- Verify project compiles:
cargo check - Verify main package test suite passes:
cargo test - Verify code on all packages is formatted:
cargo fmt --all -- --check - Lint all packages and fail also on warnings:
cargo clippy --all-targets --all-features -- -D warnings
Benchmarking
Rust bench is unstable & seems the community uses Criterion.rs.
Benchmarking the release executable
hyperfine can be used to benchmark arbitrary command line tool:
hyperfine './target/release/advent-of-code-2021'
