final class Concat[T] extends GraphStage[UniformFanInShape[T, T]]
Takes multiple streams and outputs one stream formed from the input streams by first emitting all of the elements from the first stream and then emitting all of the elements from the second stream, etc.
A Concat
has one first
port, one second
port and one out
port.
Emits when the current stream has an element available; if the current input completes, it tries the next one
Backpressures when downstream backpressures
Completes when all upstreams complete
Cancels when downstream cancels
