  1. def bidirectionalIdleTimeout[I, O](timeout: FiniteDuration): BidiFlow[I, I, O, O, NotUsed]

    If the time between two processed elements *in any direction* exceed the provided timeout, the stream is failed with a java.util.concurrent.TimeoutException.

    If the time between two processed elements *in any direction* exceed the provided timeout, the stream is failed with a java.util.concurrent.TimeoutException.

    There is a difference between this stage and having two idleTimeout Flows assembled into a BidiStage. If the timeout is configured to be 1 seconds, then this stage will not fail even though there are elements flowing every second in one direction, but no elements are flowing in the other direction. I.e. this stage considers the *joint* frequencies of the elements in both directions.

  2. def fromFlows[I1, O1, I2, O2, M1, M2](flow1: Graph[FlowShape[I1, O1], M1], flow2: Graph[FlowShape[I2, O2], M2]): BidiFlow[I1, O1, I2, O2, NotUsed]

    Wraps two Flows to create a BidiFlow.

    Wraps two Flows to create a BidiFlow. The materialized value of the resulting BidiFlow is NotUsed.

    Wraps two Flows to create a BidiFlow.

    Wraps two Flows to create a BidiFlow. The materialized value of the resulting BidiFlow is determined by the combiner function passed in the second argument list.

  4. def fromFunctions[I1, O1, I2, O2](top: Function[I1, O1], bottom: Function[I2, O2]): BidiFlow[I1, O1, I2, O2, NotUsed]

    Create a BidiFlow where the top and bottom flows are just one simple mapping stage each, expressed by the two functions.

  5. def fromGraph[I1, O1, I2, O2, M](g: Graph[BidiShape[I1, O1, I2, O2], M]): BidiFlow[I1, O1, I2, O2, M]

    A graph with the shape of a BidiFlow logically is a BidiFlow, this method makes it so also in type.
