class HTTP::Response::Body

A streamable response body, also easily converted into a string

def each

Iterate over the body, allowing it to be enumerable 
def each
  while (chunk = readpartial)
    yield chunk
  end
end

def initialize(client) 

def initialize(client)
  @client    = client
  @streaming = nil
  @contents  = nil
end

def inspect

Easier to interpret string inspect 
def inspect
  "#<#{self.class}:#{object_id.to_s(16)} @streaming=#{!!@streaming}>"
end

def readpartial(*args)

Other tags:
    See: HTTP::Client#readpartial - 
def readpartial(*args)
  stream!
  @client.readpartial(*args)
end

def stream!

Assert that the body is actively being streamed 
def stream!
  fail StateError, 'body has already been consumed' if @streaming == false
  @streaming = true
end

def to_s

Eagerly consume the entire body as a string 
def to_s
  return @contents if @contents
  fail StateError, 'body is being streamed' unless @streaming.nil?
  begin
    @streaming = false
    @contents = ''
    while (chunk = @client.readpartial)
      @contents << chunk
    end
  rescue
    @contents = nil
    raise
  end
  @contents
end
