AddEdge creates an edge between the source and the target vertex. If either vertex cannot be found, ErrVertexNotFound will be returned. If the edge a

AddVertex creates a new vertex in the graph. If the vertex already exists in the graph, ErrVertexAlreadyExists will be returned. AddVertex accepts a

DOT renders the given graph structure in DOT language into an io.Writer, for example a file. The generated output can be passed to Graphviz or other v

Edge returns the edge joining two given vertices or ErrEdgeNotFound if the edge doesn't exist. In an undirected graph, an edge with swapped source and

Len returns the total number of items in the priority queue.

Pop returns and removes the item with the lowest priority. This operation may cause a re-balance of the heap and thus scales with O(log n).

Push pushes a new item with the given priority into the queue. This operation may cause a re-balance of the heap and thus scales with O(log n).

RemoveEdge removes the edge between the given source and target vertices. If the edge cannot be found, ErrEdgeNotFound will be returned.

RemoveVertex removes the vertex with the given hash value from the graph. The vertex is not allowed to have edges and thus must be disconnected. Pote
