pub struct SystemTimeError(_);
Expand description
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.
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()),
}
Implementations
sourceimpl SystemTimeError
impl SystemTimeError
sourcepub fn duration(&self) -> Duration
pub fn duration(&self) -> 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_since
and 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()),
}
