Structs

PointerFrag

A pointer fragment represents one byte of a pointer. If the bytes are re-assembled in their original order, the pointer can be used again. Wildcard provenance is allowed to have index 0 everywhere.

ProvenanceCopy

A partial, owned list of provenance to transfer into another allocation.

ProvenanceMap

Stores the provenance information of pointers stored in memory.
