In grapl/src/rust:

- cloc shows that there are ~70,000 lines of Rust

- with `cargo tree`, I see that the project depends on ~600 crates

In my toy project:

- cloc shows that there are ~40,000 lines of Rust

- with `cargo tree`, I see ~40 crates

I don't know the scope of grapl, but 600 (transitives) crates seems a lot to me. Maybe that explains why this particular build is so long. I haven't managed to build it (seems to have prerequisites on proto buffer stuff).
