pub struct SystemTimeError(_);
An error returned from the duration_since
and elapsed
methods on
SystemTime
, used to learn how far in the opposite direction a system time
lies.
use std::thread::sleep;
use std::time::{Duration, SystemTime};
let sys_time = SystemTime::now();
sleep(Duration::from_secs(1));
let new_sys_time = SystemTime::now();
match sys_time.duration_since(new_sys_time) {
Ok(_) => {}
Err(e) => println!("SystemTimeError difference: {:?}", e.duration()),
}
Returns the positive duration which represents how far forward the
second system time was from the first.
A SystemTimeError
is returned from the duration_since
and elapsed
methods of SystemTime
whenever the second system time represents a point later
in time than the self
of the method call.
use std::thread::sleep;
use std::time::{Duration, SystemTime};
let sys_time = SystemTime::now();
sleep(Duration::from_secs(1));
let new_sys_time = SystemTime::now();
match sys_time.duration_since(new_sys_time) {
Ok(_) => {}
Err(e) => println!("SystemTimeError difference: {:?}", e.duration()),
}
