I tried Rust a few weeks ago. Is my understanding correct that Rust doesn't have the equivalents to the following C++ features yet?

- non-type and template template parameters

- constexpr functions

I understand that Rust macros can replace them some of the time, and they are much better then the C preprocessor, but that's quite a low bar to meet. Last time I checked non-type template parameters (called "const generics" in Rust) is on the roadmap, so it is promising.
