[][src]Enum rustc_mir::borrow_check::AccessDepth

enum AccessDepth {
    Shallow(Option<ArtificialField>),
    Deep,
    Drop,
}

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.
