Variants§
Shallow(Option<ArtificialField>)
From the RFC: “A shallow access means that the immediate
fields reached at P are accessed, but references or pointers
found within are not dereferenced. Right now, the only access
that is shallow is an assignment like x = ...;
, which would
be a shallow write of x
.”
Deep
From the RFC: “A deep access means that all data reachable through the given place may be invalidated or accesses by this action.”
Drop
Access is Deep only when there is a Drop implementation that can reach the data behind the reference.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
