wintrap-rs

The wintrap crate allows a Windows process to trap one or more abstracted "signals", running an asynchronous callback function whenever they are caught while active.

Examples

wintrap::trap(vec![wintrap::Signal::CtrlC, wintrap::Signal::CloseWindow], |signal| {
    // handle signal here
    println!("Caught a signal: {:?}", signal);
}, || {
    // do work
    println!("Doing work");
}).unwrap();

Caveats

Please note that it is not possible to correctly trap Ctrl-C signals when running programs via cargo run. You will have to run them directly via the target directory after building.


lib.rs:

The wintrap crate allows a Windows process to trap one or more abstracted "signals", running a callback function in a dedicated thread whenever they are caught while active.

Examples

wintrap::trap(&[wintrap::Signal::CtrlC, wintrap::Signal::CloseWindow], |signal| {
    // handle signal here
    println!("Caught a signal: {:?}", signal);
}, || {
    // do work
    println!("Doing work");
}).unwrap();
