# Error code E0770

The type of a const parameter references other generic parameters.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    fn foo<T, const N: T>() {} // error!
    }

To fix this error, use a concrete type for the const parameter:

    #![allow(unused)]
    fn main() {
    fn foo<T, const N: usize>() {}
    }
