Struct SignalHandler

pub struct SignalHandler { /* private fields */ }

Implementations

impl SignalHandler

pub fn with_termination_signals(termination_signals: &[i32]) -> Self

Override the default termination signals list.

pub fn add_termination_signal(&mut self, signal: i32)

pub fn termination_pending(&mut self) -> bool

Returns true if there are unprocessed termination signals.

This is useful for checking for termination signals in between different stages of processing, so that the application responds fast to signals.

  let mut sh = SignalHandler::default();
  println!("Try using ctrl+c.");
  loop {
    if sh.termination_pending() {
      println!("Termination signal received.");
      break;
    }
    std::thread::sleep(std::time::Duration::from_millis(100));
