# Error code E0263

#### Note: this error code is no longer emitted by the compiler.

A lifetime was declared more than once in the same scope.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    fn foo<'a, 'b, 'a>(x: &'a str, y: &'b str, z: &'a str) { // error!
    }
    }

Two lifetimes cannot have the same name. To fix this example, change the second `'a` lifetime into something else (`'c` for example):

    #![allow(unused)]
    fn main() {
    fn foo<'a, 'b, 'c>(x: &'a str, y: &'b str, z: &'c str) { // ok!
    }
    }
