Align	[Unstable] Alignment of a type in bytes, both ABI-mandated and preferred. Since alignments are always powers of 2, we can pack both in one byte, giving each a nibble (4 bits) for a maximum alignment of 2¹⁵ = 32768.
Size	[Unstable] Size of a type in bytes.
Struct	[Unstable] A structure, a product type in ADT terms.
TargetDataLayout	[Unstable] Parsed Data layout for a target, which contains everything needed to compute layouts.

Endian	[Unstable] Endianness of the target, which must match cfg(target-endian).
Integer	[Unstable] Integers, also used for enum discriminants.
Layout	[Unstable] Type layout, from which size and alignment can be cheaply computed. For ADTs, it also includes field placement and enum optimizations. NOTE: Because Layout is interned, redundant information should be kept to a minimum, e.g. it includes no sub-component Ty or Layout.
LayoutError	[Unstable]
Primitive	[Unstable] Fundamental unit of memory access and layout.
SizeSkeleton	[Unstable] Type size "skeleton", i.e. the only information determining a type's size. While this is conservative, (aside from constant sizes, only pointers, newtypes thereof and null pointer optimized enums are allowed), it is enough to statically check common usecases of transmute.

FAT_PTR_ADDR	[Unstable] The first half of a fat pointer. - For a trait object, this is the address of the box. - For a slice, this is the base address.
FAT_PTR_EXTRA	[Unstable] The second half of a fat pointer. - For a trait object, this is the address of the vtable. - For a slice, this is the length.
