Expand description
Access to all edges of each node, in the specified direction.
The edges are, depending on the direction and the graph’s edge type:
Directed
,Outgoing
: All edges froma
.Directed
,Incoming
: All edges toa
.Undirected
,Outgoing
: All edges connected toa
, witha
being the source of each edge.Undirected
,Incoming
: All edges connected toa
, witha
being the target of each edge.
This is an extended version of the trait IntoNeighborsDirected
; the former
only iterates over the target node identifiers, while this trait
yields edge references (trait EdgeRef
).
