pub unsafe trait Region { }Expand description
A contiguous memory region.
Each type that implements Region corresponds to a single allocated object
at runtime. That Region type is said to “contain” some memory segment if
the segment is completely contained within the bounds of the allocated
object. While each region must correspond to a single allocated object, each
allocated object may correspond with multiple Region types.
If memory segments are contained in the same region type, then computing the
the offset between them is guaranteed to be safe. However, because different
Region types may correspond with the same allocated object, computing the
offset betwewen memory segments in different regions may or may not be safe.
Note that while a type implementing Region must correspond with a single
allocated object, it does not need to know anything about that allocated
object.
Safety
This type must correspond to a single unique allocated object.
