Instance Method Details

#accept ⇒ Object

Invokes ‘accept_nonblock` on the underlying io. If the operation would block, the current task is paused until the operation can succeed, at which point it’s resumed and the operation is completed.

#connect ⇒ Object

Invokes ‘connect_nonblock` on the underlying io. If the operation would block, the current task is paused until the operation can succeed, at which point it’s resumed and the operation is completed.
