3 Erroneous code example:
13 x: 0, // error: field `x` specified more than once
18 This error indicates that during an attempt to build a struct or struct-like
19 enum variant, one of the fields was specified more than once. Each field should
20 be specified exactly one time. Example:
28 let x = Foo { x: 0 }; // ok!
