# Error code E0800

A type or const parameter of the given name is not in scope.

Erroneous code examples:

    #![allow(unused)]
    fn main() {
    fn missing() -> impl Sized + use<T> {}
    }

To fix this error, please verify you didn't misspell the type or const parameter, or double-check if you forgot to declare the parameter in the list of generics.
