Package digraph6 implements graphs specified by digraph6 strings.
IsValid returns whether the graph is a valid digraph6 encoding. An invalid Graph behaves as the null graph.
Graph is a digraph6-represented directed graph.
See https://users.cecs.anu.edu.au/~bdm/data/formats.txt for details.
Note that the digraph6 format specifies that the first character of the graph string is a '&'. This character must be present for use in the digraph6 package. A Graph without this prefix is treated as the null graph.
Encode returns a graph6 encoding of the topology of the given graph using a lexical ordering of the nodes by ID to map them to [0, n).
Edge returns the edge from u to v, with IDs uid and vid, if such an edge exists and nil otherwise. The node v must be directly reachable from u as defined by the From method.
From returns all nodes that can be reached directly from the node with the given ID.
HasEdgeBetween returns whether an edge exists between nodes with IDs xid and yid without considering direction.
HasEdgeFromTo returns whether an edge exists in the graph from u to v with IDs uid and vid.
Node returns the node with the given ID if it exists in the graph, and nil otherwise.
Nodes returns all the nodes in the graph.
To returns all nodes that can reach directly to the node with the given ID.
