# Error code E0415

More than one function parameter have the same name.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    fn foo(f: i32, f: i32) {} // error: identifier `f` is bound more than
                              //        once in this parameter list
    }

Please verify you didn’t misspell parameters’ name. Example:

    #![allow(unused)]
    fn main() {
    fn foo(f: i32, g: i32) {} // ok!
    }
