pub struct SystemTimeError(/* private fields */);
Expand description
An error returned from the duration_since
and elapsed
methods onSystemTime
, used to learn how far in the opposite direction a system time lies.
§Examples
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 SystemTime::duration_sinceand SystemTime::elapsed methods whenever the second system time represents a point later in time than the self
of the method call.
§Examples
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()),
}
