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