Struct twizzler_object::slot::Slot
source · pub struct Slot { /* private fields */ }Expand description
A slot for an object in active memory. All unique combinations of an object ID and Protections are given a slot. The exact slot locations may be reused. Typically, slots are reference counted, and when dropped, release the slot for reuse. The object may or may not be unmapped immediately following the slot’s drop.
