Packaging Rust Applications with Nix

See codex for an example.

Updating an Existing Rust Package

Besides the general update steps, also update the cargoHash:

# Set cargoHash = ""; then run nix build
# Nix will fail and show: "got: sha256-XXXXX"

If Cargo.toml dependencies changed, the build will automatically fetch new dependencies after you update the cargoHash.
