Fields

bytes: Vec<u8>

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

relocations: BTreeMap<u64, AllocId>

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
