topological_generations(dag, /)

Return the topological generations of a DAG

A topological generation is node collection in which ancestors of a node in each generation are guaranteed to be in a previous generation, and any descendants of a node are guaranteed to be in a following generation. Nodes are guaranteed to be in the earliest possible generation that they can belong to.

Parameters:

graph (PyDiGraph) – The DAG to get the topological generations from

Returns:

A list of topological generations.

Return type:

list

Raises:

DAGHasCycle – if a cycle is encountered while sorting the graph
