Trait Clock

Source

pub trait Clock: Send + Sync {
    // Required method
    fn now_ms(&self) -> TimestampMs;
}

Expand description

A source of wall-clock time. Injected into crate::Grit via crate::Options; tests inject ManualClock for full determinism.

Contract: implementations should return non-negative values (times at or after the Unix epoch). grit clamps negative readings to 0 wherever they would feed an HLC — the sortable HLC encoding is only order-preserving for non-negative wall times.

§Example

use grit_core::{Clock, ManualClock};
let clock = ManualClock::new(1_000);
assert_eq!(clock.now_ms(), 1_000);
clock.advance_ms(5);
assert_eq!(clock.now_ms(), 1_005);
