MockClock

Struct MockClock 

Source
pub struct MockClock { /* private fields */ }
Expand description

Mock clock for deterministic testing.

Time only advances when explicitly told to, enabling fully reproducible test scenarios.

§Example

use grate_limiter::{MockClock, Clock};
use std::sync::Arc;

let clock = Arc::new(MockClock::new());
assert_eq!(clock.now().as_millis(), 0);

clock.advance_ms(5000);
assert_eq!(clock.now().as_millis(), 5000);
