Dockerfile

# Source: https://alexbrand.dev/post/how-to-package-rust-applications-into-minimal-docker-containers/,

# Dockerfile for creating a statically-linked Rust application using docker's
# multi-stage build feature. This also leverages the docker build cache to avoid
# re-downloading dependencies if they have not changed.
