Module clock 

Clock abstraction for deterministic time-dependent testing.

Inject Clock into any component that calls SystemTime::now(), enabling unit tests to control time without real-time delays.

Usage

Production code should accept Arc<dyn Clock> and use SystemClock as the default:

use std::sync::Arc;
use fraiseql_core::utils::clock::{Clock, SystemClock};

struct MyComponent {
    clock: Arc<dyn Clock>,
}

impl MyComponent {
    pub fn new() -> Self {
        Self { clock: Arc::new(SystemClock) }
    }

    pub fn new_with_clock(clock: Arc<dyn Clock>) -> Self {
        Self { clock }
    }
}

Structs

SystemClock

Production clock: delegates to SystemTime::now().

Traits
