Latest crates.io version is from 2021

[ramarivera]

First of all, I'm kind of newish to Rust and how it manages dependencies, so I apologize if this question has a very obvious answer :)

The latest published version of this library in crates.io is 2.0.1, which is from 2021.

But I can see that in the last two years some things changed with this library, for example, it currently doesn't depend on harfbuzz-sys anymore.

So my question is, how can I install this library, and at the same time specify which version of harfbuzz to actually use?

I know I can point to a commit or branch in Cargo.toml, but that isn't compatible with later publishing said crate to crates.io.

Is it expected to link to this repo as a git submodule?

Thanks in advance for your time!
