def close(error = nil) -> close the stream immediately.

The consumer can call stop to signal that the stream output has terminated.

def each

Enumerate all chunks until finished, then invoke `#close`. 
def each
	while chunk = self.read
		yield chunk
		# chunk.clear
	end
ensure
	self.close($!)
end

def empty?

Will read return any data? 
def empty?
	false
end

def finish

Read all remaining chunks into a buffered body and close the underlying input. 
def finish
	# Internally, this invokes `self.each` which then invokes `self.close`.
	Buffered.for(self)
end

def join

Read all remaining chunks into a single binary string using `#each`. 
def join
	buffer = String.new.force_encoding(Encoding::BINARY)
	
	self.each do |chunk|
		buffer << chunk
		chunk.clear
	end
	
	return buffer

def length
	nil
end

def read

Read the next available chunk.
