class Protocol::HTTP::Body::Streamable::RequestBody

As the response body isn’t available until the request is sent, the response body must be {stream}ed into the request body.
A request body is used on the client side to generate the request body using a block.

def close(error = nil) 

def close(error = nil)
	# Close will be invoked when all the input is read.
	self.close_input(error)
end

def initialize(block) 

def initialize(block)
	super(block, Writable.new)
end

def stream(body)

Stream the response body into the block's input. 
def stream(body)
	body&.each do |chunk|
		@input.write(chunk)
	end
rescue => error
ensure
	@input.close_write(error)
end
