Trait Clock 

pub trait Clock:
    Send
    + Sync
    + Debug {
    // Required method
    fn now_millis(&self) -> u64;
}

A source of milliseconds.

Implementations must be cheap to call (it happens on every report) and must never panic. The absolute epoch is deliberately unspecified: atune only ever computes differences and compares against caller-supplied deadlines, so a clock that starts at zero is as valid as one that returns Unix time.

Monotonicity is expected but not enforced; consumers must tolerate a backwards step (for instance by saturating the subtraction) rather than panicking.

Required Methods

fn now_millis(&self) -> u64

The current time, in milliseconds since this clock’s epoch.

Dyn Compatibility

This trait is dyn compatible.

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