Struct SystemClock 

pub struct SystemClock;

Available on crate feature std only.

A clock backed by the operating system.

SystemClock forwards Clock::now to Monotonic::now and Clock::wall to Wall::now. It is zero-sized, Copy, and the constructor is const, so it imposes no runtime cost over calling the free functions directly.

Examples

use clock_lib::{Clock, SystemClock};

const CLOCK: SystemClock = SystemClock::new();
let t = CLOCK.now();

Implementations
