|
* Used to create an anonymous union of two structs with identical layout
|
|
* and size: one anonymous and one named. The former's members can be used
|
|
* normally without sub-struct naming, and the latter can be used to
|
|
* reason about the start, end, and size of the group of struct members.
|
|
* The named struct can also be explicitly tagged for layer reuse, as well
|
|
* as both having struct attributes appended.
