Trait EdgeTargetGraph 

pub trait EdgeTargetGraph: TopologyBase {
    // Required method
    fn target(&self, edge: Self::RelationId) -> Self::ElementId;
}

Capability for resolving directed edge targets.

The endpoint capability needed by outgoing traversal: an outgoing edge ID can be mapped to the node it reaches without requiring the backend to support reverse source lookup.

Required Methods

fn target(&self, edge: Self::RelationId) -> Self::ElementId

Returns the target node of edge. edge must be a valid edge ID.

Dyn Compatibility

This trait is dyn compatible.

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