signature Socket.Buffer where

import Prelude (Int)

-- A buffer that needs to be either filled or consumed.

-- the buffer until the length is 0. At that point, the
-- buffer has been entirely filled or consumed.
data Buffer

-- Move forward in the buffer. Callers of this function
-- are responsible for checking bounds.
advance :: Buffer -> Int -> Buffer
