pub(crate) const HEARTBEAT_DEAD: Duration;Expand description
How long a ping may go unanswered before the connection is reaped. Four missed beats: long enough that a busy peer is never cut, short enough that a role is not held by a corpse for the minutes a TCP retransmission timeout takes. Chosen, not measured: the one number it changes for a person is how fast a call on a paused host fails (a tool call’s own bound is longer).
