Sleeps for a while and returns the control flow afterwards. Can be used to check for user input (eg: CTRL+C) while sleeping or updating a status bar.
rust
let total = std::time::Duration::from_secs(1); // Sleeping for a total of 1 s
let len = std::time::Duration::from_millis(100); // Interrupting the sleep after 100 ms
let snoozy = isleep::IntermittentSleeping::new(total); // `total` start at class initialization
// while snoozy.accurate_snooze(len): // <- higher accuracy with the `accuracy` feature
while snoozy.snooze(len) {
println!("Checking if the user pressed CTRL+C...");
}
cargo add isleep --features=accuracy
The accuracy of sleep duration is depending on the operating system.
Sleeping for less than 15 ms won't work reliably (eg: on Windows).
For more accurate sleeping the accuracy feature and the accurate_snooze function can be used.
This relies on the spin-sleep crate for improved accuracy.
