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
