pub fn spawn_handler(token: CancellationToken)Expand description
Spawn a task that cancels token on SIGTERM or SIGINT, and logs SIGHUP
(config reload is not yet implemented).
ยงPanics
Panics if the process cannot install the SIGTERM/SIGINT/SIGHUP handlers (e.g. the signal already has a conflicting handler). This is a fatal startup condition.
