Rust Functions Are Weird (But Be Glad)

Описание: Rust takes a unique approach to function types, for both closures and fn items. In this video we'll talk about a way to fit these strange function types into your existing understanding of what types are. Then we'll look at how another language (okay, it's C++) does function types in a way that causes poor codegen in generic higher-order functions if you aren't careful--and how/why Rust avoids this problem.
