Struct ThreadCpuClock 

pub struct ThreadCpuClock;

The CPU time the calling thread has used, CLOCK_THREAD_CPUTIME_ID.

Read through a system call, not the fast path the clocks above take. Two readings on two threads count two different times.

Examples

use core::hint::black_box;

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

let start = ThreadCpuClock.now();
for value in 0_u64..1_000_000 {
    black_box(value);
}
assert!(ThreadCpuClock.now() - start > Timedelta::ZERO, "the loop took CPU time");
