Trait Clock 

pub trait Clock: Send + Sync {
    // Required methods
    fn monotonic_millis(&self) -> u64;
    fn epoch_seconds(&self) -> u64;
}

Clock used for wall-clock timestamps and monotonic elapsed durations.

Production code normally uses SystemClock. Tests and reproducible harnesses can inject FixedClock or a domain-specific implementation.

Required Methods

fn monotonic_millis(&self) -> u64

Monotonic milliseconds used for elapsed-duration measurements.

fn epoch_seconds(&self) -> u64

Unix epoch seconds used for wall-clock timestamps.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
