\typedef igraph_neimode_t \brief How to interpret edge directions in directed graphs?
These “neighbor mode” constants are typically used to specify the treatment of edge directions in directed graphs, or which vertices to consider as adjacent to (i.e. neighbor of) a vertex. It is typically ignored in undirected graphs.
\enumval IGRAPH_OUT Follow edge directions in directed graphs, or consider out-neighbors of vertices. \enumval IGRAPH_IN Follow edges in the reverse direction in directed graphs, or consider in-neighbors of vertices. \enumval IGRAPH_ALL Ignore edge directions in directed graphs, or consider all neighbours (both out and in-neighbors) of vertices.
