struct uint128_struct

Stores a 128-bit quantity.

This structure is organized so that 128-bit quantities are laid out in

memory according to the system’s natural byte order. If a system offers a

native 128-bit type, it should be possible to bit_cast

<

> between that type

and this one.

This structure is designed to have the same layout, although not the same

field names, as the Windows SDK’s `M128A` type from `

<winnt

.h>`. It is

provided here instead of in `compat` because it is useful outside of the

scope of data structures defined by the Windows SDK.
