The actual bytes of the allocation. Note that the bytes of a pointer represent the offset of the pointer

Maps from byte addresses to allocations. Only the first byte of a pointer is inserted into the map.
undef_mask: UndefMask

Denotes undefined memory. Reading from undefined memory is forbidden in miri
align: Align

The alignment of the allocation to detect unaligned reads.
runtime_mutability: Mutability

Whether the allocation (of a static) should be put into mutable memory when translating
Only happens for static mut
or static
with interior mutability
