+
+Hello world Rust project for verifying Gitea Actions build cache.
+
+## What this tests
+
+1. `go-hashfiles` generates a hash from `Cargo.lock` and `Cargo.toml`
+2. `actions/cache@v3` caches `~/.cargo/registry`, `~/.cargo/git`, and `target`
+3. Subsequent runs should hit the cache and skip recompilation
+
+## Run locally
+
+```bash
+cargo build
+cargo run
+```
