“If you're coming from C++ template metaprogramming, then macro_rules! is a blessing. And I love it! But also part of the value of Rust is that you don't have to fall back to duck-typed templating. Typically, you should be able to solve your problems with just generics, and in doing so benefit fro
“CRTP mostly solves problems around inheritance, which Rust doesn't really have. There's very limited support for inheritance in the form of supertraits, but it works quite differently from C++ derived classes, so I don't think you run into the same kinds of issues. Variadic generics don't exist,
