Description

Materializes this Graph, immediately returning (1) its materialized value, and (2) a new pre-materialized Graph.

Note that preMaterialize is implemented through a reactive streams Publisher for a Source or a Publisher and Subscriber pair for a Flow which means that a buffer is introduced and that errors are not propagated upstream but are turned into cancellations without error details.
