Variants§
AlwaysSized

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).

attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
