module Reel
  # Base class for Reel servers.
  #
  # This class is a Celluloid::IO actor which provides a barebones server
  # which does not open a socket itself, it just begin handling connections once
  # initialized with a specific kind of protocol-based server.

  # For specific protocol support, use:

  # Reel::Server::HTTP
  # Reel::Server::HTTPS
  # Coming soon: Reel::Server::UNIX

  class Server
    include Celluloid::IO
    # How many connections to backlog in the TCP accept queue
    DEFAULT_BACKLOG = 100
