# Error code E0124

A struct was declared with two fields having the same name.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    struct Foo {
        field1: i32,
        field1: i32, // error: field is already declared
    }
    }

Please verify that the field names have been correctly spelled. Example:

    #![allow(unused)]
    fn main() {
    struct Foo {
        field1: i32,
        field2: i32, // ok!
    }
    }
