Comment:
Maybe we can do a cleanup by adding a `do_configure` to the cargo build style.

```
do_configure() {
     cargo fetch --target ${RUST_TARGET} ${configure_args}
}
```

From the docs of `cargo-fetch`
> If a `Cargo.lock` file is available, this command will ensure that all of the git dependencies and/or registry dependencies are downloaded and locally available. Subsequent Cargo commands will be able to run offline after a cargo fetch unless the lock file changes.
>
> If the lock file is not available, then this command will generate the lock file before fetching the dependencies.
