To avoid redownloading all crate dependencies during continuous integration, you can cache the `$CARGO_HOME` directory.
However, caching the entire directory is often inefficient as it will contain downloaded sources twice.
If we depend on a crate such as `serde 1.0.92` and cache the entire `$CARGO_HOME` we would actually cache the sources twice, the `serde-1.0.92.crate` inside `registry/cache` and the extracted `.rs` files of serde inside `registry/src`.
