via[Out2, Ctx2, Mat2](flow: Graph[FlowShape[(Out, Ctx), (Out2, Ctx2)], Mat2]): Repr[Out2, Ctx2]
Transform this flow by the regular flow.
Transform this flow by the regular flow. The given flow must support manual context propagation by taking and producing tuples of (data, context).
This can be used as an escape hatch for operations that are not (yet) provided with automatic context propagation here.

Transform this flow by the regular flow.
Transform this flow by the regular flow. The given flow must support manual context propagation by taking and producing tuples of (data, context).
This can be used as an escape hatch for operations that are not (yet) provided with automatic context propagation here.
The
combine
function is used to compose the materialized values of this flow and that flow into the materialized value of the resulting Flow.
