Trait EdgeSourceGraph 

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

Capability for resolving directed edge sources.

Separated from EdgeTargetGraph because some layouts (e.g. outgoing-only CSR) can resolve targets cheaply but need extra indexing for sources.

Required Methods

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

Returns the source 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".
