Enum rustc_middle::ty::layout::StructKind

source ·

enum StructKind {
    AlwaysSized,
    MaybeUnsized,
    Prefixed(Size, Align),
}

Variants

`AlwaysSized`

A tuple, closure, or univariant which cannot be coerced to unsized.

`MaybeUnsized`

A univariant, the last field of which may be coerced to unsized.

`Prefixed(Size, Align)`

A univariant, but with a prefix of an arbitrary size & alignment (e.g., enum tag).
