For all these, individual fields are aligned to their preferred alignment. For
|
|
|
|
|
primitives this is usually equal to their size. For instance, a u32 will be
|
|
|
|
|
aligned to a multiple of 32 bits, and a u16 will be aligned to a multiple of 16
|
|
|
|
|
bits. Composite structures will have a preferred alignment equal to the maximum
|
|
|
|
|
bits. Note that some primitives may be emulated on different platforms, and as
|
|
|
|
|
such may have strange alignment. For instance, a u64 on x86 may actually be
|
|
|
|
|
emulated as a pair of u32s, and thus only have 32-bit alignment.

Composite structures will have a preferred alignment equal to the maximum

of their fields' preferred alignment, and a size equal to a multiple of their

preferred alignment. This ensures that arrays of T can be correctly iterated

by offsetting by their size. So for instance,
