MinimalSleeper

Struct MinimalSleeper 

Source
pub struct MinimalSleeper {
    min_sleep: Duration,
    sleep_owed: SignedDuration,
    total_cumulative_sleep: Duration,
}
Expand description

MinimalSleeper provides a facility for periodically sleeping such that on average we sleep for the requested amount of time, even though we don’t necessarily sleep on every call. The idea is to be efficient in the use of system calls.

§Examples

use std::time::Duration;
use cpu::MinimalSleeper;
// `s` will try to sleep, on average, for the indicated amounts
// of time, but will never sleep for less than 1 millisecond.
let mut s = MinimalSleeper::new(Duration::from_millis(10));

Fields§

§min_sleep: Duration

Minimum period for which we will try to sleep.
