Struct ctrlc::CtrlC

pub struct CtrlC;

Implementations

impl CtrlC

pub fn set_handler<F>(user_handler: F) where
    F: Fn() + 'static + Send, 

Sets up the signal handler for Ctrl-C using default polling rate of 100ms.

Example

CtrlC::set_handler(|| println!("Hello world!"));

pub fn set_handler_with_polling_rate<F>(user_handler: F, polling_rate: Duration) where
    F: Fn() + 'static + Send, 

Sets up the signal handler for Ctrl-C using a custom polling rate. The polling rate is the amount of time the internal spinloop of CtrlC sleeps between iterations. Because condition variables are not safe to use inside a signal handler, CtrlC (from version 1.1.0) uses a spinloop and an atomic boolean instead.

Normally you should use set_handler instead, but if the default rate of 100 milliseconds is too fast or too slow for you, you can use this routine instead to set your own.

Example

CtrlC::set_handler_with_polling_rate(
    || println!("Hello world!"),
    Duration::from_millis(10)
);
