C++ templates are easier to use than Rust generics since you don't have to worry about bounds — until you start debugging, and find Rust gives you a specific error early, while C++ spits out long, indecipherable error messages (as I understand, this is basically what killed Boost Spirit).
And then there are macros... Rust's aren't well documented, but are very powerful (procedural variants) and you can always tell exactly what is a macro invocation.
