Struct MonotonicClock 

pub struct MonotonicClock;

Available on 64-bit and crate feature std and (Linux or macOS) only.

The monotonic clock: CLOCK_MONOTONIC on Linux, CLOCK_UPTIME_RAW on macOS.

It never steps, and every process on the machine reads the same clock, which makes it the clock for a deadline. It stops while the machine sleeps. Linux lets a time service slew its rate; macOS does not.

Examples

use t2t_clock::{Clock, MonotonicClock};
use t2t_core::Timedelta;

let deadline = MonotonicClock.now() + Timedelta::from_millis(50);
assert!(MonotonicClock.now() < deadline, "the deadline lies ahead");
