      Parameters:
      supplier - the supplier, must return a non-null Uni
      Returns:
      the new Multi

    • failWith

      @CheckReturnValue public Multi<T> failWith(Throwable failure)
      When the current Multi completes, the passed failure is sent downstream.
      Parameters:
      failure - the failure
      Returns:
      the new Multi

    • failWith

      @CheckReturnValue public Multi<T> failWith(Supplier<Throwable> supplier)
      When the current Multi completes, a failure produced by the given Supplier is sent downstream.
      Parameters:
      supplier - the supplier to produce the failure, must not be null, must not produce null
