Expand description
Exponential-backoff probe scheduler.
Starts at DiscoveryConfig::hello_interval_base and doubles on each tick
where no probe is needed, up to DiscoveryConfig::hello_interval_max.
Jitter of ±DiscoveryConfig::hello_jitter × interval is applied to
each computed deadline to desynchronise nodes that started simultaneously.
§Reset behaviour
Any TriggerEvent resets the interval to the base and sets
pending_immediate = true so that the very next [on_tick] call emits
a ProbeRequest::Broadcast without waiting for the deadline. A
successful probe ([on_probe_success]) similarly resets the interval; a
probe timeout ([on_probe_timeout]) advances to the next (doubled) level.
