Trait sophia_api::dataset::SetDataset
source · pub trait SetDataset: Dataset { }Expand description
Marker trait constraining the semantics of
Dataset and MutableDataset.
It guarantees that (1) quads will never be returned / stored multiple times.
If the type also implements MutableDataset,
it must also ensure that
(2) the bool or usize values returned by MutableDataset
methods accurately describe how many quads were actually added/removed.
Note to implementors
A type implementing both Dataset and MutableDataset,
enforcing (1) but failing to enforce (2)
must not implement this trait.
Object Safety§
This trait is not object safe.
