mono_nanos

fn mono_nanos() -> int

use clock::{mono_nanos};

Returns monotonic nanoseconds from a process-local starting point.

The value never goes backwards and is unrelated to wall time: only the difference between two readings means something.

Returns#

int

Examples#

use clock::{mono_nanos, sleep_ms};
use tests::assert;
let start = mono_nanos();
sleep_ms(5);
let elapsed_ms = (mono_nanos() - start) / 1000000;
assert!(elapsed_ms >= 5);

• wall_nanos: Returns the current wall-clock time in nanoseconds since the Unix epoch (UTC).
• sleep_ms: Pauses for at least ms milliseconds.
