"The image shows a terminal screenshot with commands and outputs related to upgrading Rust packages using `cargo`. Key points include:
- **Top section**:
- A full `git` checkout of the Cargo registry is taking up significant space (881MB), prompting the user to clean it up with the `rm -rf ~/.cargo/registry/src/` command.
- **Middle section**:
- After clearing the registry, the user runs `cargo upgrade -p rubicon`, using version `v1.81.0` and the sparse registry. The process checks dependencies and upgrades package versions (upgrading `rubicon` to version `3.4.7`), taking approximately 2.278 seconds.
- **Bottom section**:
- After using the sparse registry, only 38MB is utilized in the `.cargo/registry/src/` directory, highlighting the efficiency of fetching a few subdirectories over HTTP instead of using `git`.
Annotations on the image include:
- Red text explaining that the full `git` checkout took minutes and was removed.
- Yellow text pointing out that `cargo-upgrade 0.13` took just 2.3 seconds to upgrade using the sparse registry.
- Green text noting the smaller space consumption after switching to fetching over HTTP."
