The file is named Cargo.toml. Whatever dependencies you add to there are automatically downloaded by Cargo. You can manage them with cargo add
and cargo remove
.
cargo install

I was vaguely aware that some ancient architectures had weird byte widths, but I did not know about this. Pretty interesting.
