You're conflating traits with generics. Generics exist without traits, and in Rust they are more closely aligned with C++ templates than anything else, since they are implemented via monomorphisation, whereas in Haskell they are not. Regardless, Rust is not "patterned" after a single other language. It's influenced by many langauges, so it makes no sense to say that one feature is just copied straight from a specific other language.
