# Error code E0062

A struct’s or struct-like enum variant’s field was specified more than once.

Erroneous code example:

    struct Foo {
        x: i32,
    }

    fn main() {
        let x = Foo {
                    x: 0,
                    x: 0, // error: field `x` specified more than once
                };
    }

This error indicates that during an attempt to build a struct or struct-like enum variant, one of the fields was specified more than once. Each field should be specified exactly one time. Example:

    struct Foo {
        x: i32,
    }

    fn main() {
        let x = Foo { x: 0 }; // ok!
    }
