Documentation

Overview

The `timing` module provides std::time utility functions. use std::time::Duration; use std::time::{SystemTime, UNIX_EPOCH};

pub fn duration_as_us(d: &Duration) -> u64 {
    (d.as_secs() * 1000 * 1000) + (u64::from(d.subsec_nanos()) / 1_000)
}

pub fn duration_as_ms(d: &Duration) -> u64 {
    (d.as_secs() * 1000) + (u64::from(d.subsec_nanos()) / 1_000_000)
}

pub fn duration_as_s(d: &Duration) -> f32 {
    d.as_secs() as f32 + (d.subsec_nanos() as f32 / 1_000_000_000.0)
}

pub fn timestamp() -> u64 {
    let now = SystemTime::now()
        .duration_since(UNIX_EPOCH)
        .expect("create timestamp in timing");
    duration_as_ms(&now)
}
