One can specify a particular layout using the [`repr` attribute](#ffi-attributes). -By using the `struct_inherit` feature gate, structures may use single -inheritance. A Structure may only inherit from a single other structure, called -the _super-struct_. The inheriting structure (sub-struct) acts as if all fields -in the super-struct were present in the sub-struct. Fields declared in a -sub-struct must not have the same name as any field in any (transitive) -super-struct. All fields (both declared and inherited) must be specified in any -initializers. Inheritance between structures does not give subtyping or -coercion. The super-struct and sub-struct must be defined in the same crate. -The super-struct must be declared using the `virtual` keyword. For example: - -```{.ignore} -virtual struct Sup { x: int } -struct Sub : Sup { y: int } -let s = Sub {x: 10, y: 11}; -let sx = s.x; -``` - ### Enumerations An _enumeration_ is a simultaneous definition of a nominal [enumerated |
