Trait ContainsRelation 

pub trait ContainsRelation: TopologyBase {
    // Required method
    fn contains_relation(&self, relation: Self::RelationId) -> bool;
}

Relation-ID containment capability for a topology view.

This capability answers whether a relation ID is valid and visible in this view at the time of the call. It does not answer graph-specific questions such as whether an edge between two nodes exists, nor hypergraph-specific questions such as whether a vertex participates in a hyperedge.

Performance

Expected O(1) unless the implementation documents otherwise.

Required Methods

fn contains_relation(&self, relation: Self::RelationId) -> bool

Returns whether relation is valid and visible in this view.

Performance

Expected O(1) unless the implementation documents otherwise.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
