Forgive me, I didn't intend to be so argumentative. I genuinely want to understand. I'm trying to figure out if there are whole categories of use cases that I just don't have any exposure to.
As a side note: I keep trying Rust over and over again, and just can't get in to it. I think my brain just doesn't work that way. For my hobby project that needs super low level perf, I've moved a codebase from C, to Rust, and now to http://terralang.org/ and I'm finally quite satisfied with how the project is going.
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.
