As I understand it, generics are just a particular mechanism for interfacing with multiple types, and C manages without. For the same program, could a programmer ever be more unaware about which types are parameterized and which specific implementations are called in Rust than in C? I don't have much knowledge of C, admittedly, so this isn't a rhetorical question.
