Constructor Details

#initialize(endpoints = nil, linger: Float::INFINITY, send_hwm: nil, recv_hwm: nil, send_timeout: nil, recv_timeout: nil, backend: nil, &block) ⇒ DEALER

Returns a new instance of DEALER.

Parameters:

  • endpoints (String, nil) (defaults to: nil) —

    endpoint to bind/connect

  • linger (Numeric) (defaults to: Float::INFINITY) —

    linger period in seconds (Float::INFINITY = wait forever, 0 = drop)

  • send_hwm (Integer, nil) (defaults to: nil) —

    send high water mark

  • recv_hwm (Integer, nil) (defaults to: nil) —

    receive high water mark

  • send_timeout (Numeric, nil) (defaults to: nil) —

    send timeout in seconds

  • recv_timeout (Numeric, nil) (defaults to: nil) —

    receive timeout in seconds

  • backend (Symbol, nil) (defaults to: nil) —

    :ruby (default) or :ffi
