pub struct NullStorage<T>(_);
Expand description

Trait Implementations
Clean the storage given a bitset with bits set for valid indices. Allows us to safely drop the storage. Read more
Tries reading the data associated with an Index
.
This is unsafe because the external set used
to protect this storage is absent. Read more
Tries mutating the data associated with an Index
.
