Function signal_handler::take_signal_handler

pub fn take_signal_handler(signal: Signal) -> Option<Box<dyn SignalHandler>>

Take the SignalHandler registered for the given signal for the current task.

This removes the signal handler registered for this signal for the current task. Thus, if another exception occurs that triggers this signal, the returned handler will no longer exist to be invoked. You’d need to re-register another handler for it using register_signal_handler.
