Struct CoarseMonotonicClock 

pub struct CoarseMonotonicClock;

The monotonic clock as the kernel’s timer last left it: CLOCK_MONOTONIC_COARSE on Linux, CLOCK_UPTIME_RAW_APPROX on macOS.

The point MonotonicClock names, to the timer’s period, a few milliseconds: right for a deadline that is far off, or polled often.

Examples

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

let expiry = CoarseMonotonicClock.now() + Timedelta::from_secs(30);
assert!(CoarseMonotonicClock.now() < expiry, "a heartbeat's expiry, polled cheaply");
