Naw, it was my response that was more so than I wanted it to be. No worries. :)

Rust focuses on "zero-cost abstractions", that is, if you had to implement a feature yourself, you couldn't do it any better.

So this library, while more complex than a straightforward binding, has more features that are useful, like increased safety, while also being faster. A win-win. And very much in line with Rust's overall philosophy.
