For example, it should be easy enough to build test::black_box with this, right?

No, sadly you cannot implement equivalent for black_box without inline assembly. While there are many ways to implement a function which inhibits optimisations for a value, only the implementation with inline assembly is able to compile down to literally nothing.

As for the tutorials, there’s number of examples in the tests directory. That being said, I don’t recommend using this crate yet.
