Struct std::time::SystemTimeError

1.8.0 · source · []
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()),
}
Run

Implementations

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()),
}
Run
