class Async::HTTP::Protocol::HTTP2::Stream

@parameter error [Exception | Nil] The error which closed the input.
@parameter input [Input] The input body being closed.
Close the application-facing receiving side of the stream. While local output remains active, incoming data is discarded with flow-control updates. Once local output is also closed, the remaining wire stream is terminated without an error.

		@input = nil
		@input_closed = true
		
		if error
			send_reset_stream(::Protocol::HTTP2::Error::INTERNAL_ERROR)
		else
			close_if_finished
