Trait Clock 

pub trait Clock {
    // Required method
    fn now_unix(&self) -> u64;

    // Provided method
    fn sleep(&self, dur: Duration) { ... }
}

Supplies the current time. Injected so time-dependent logic (journal timestamps, run ages) is deterministic under test.

Required Methods

fn now_unix(&self) -> u64

Current time as whole seconds since the Unix epoch.

Provided Methods

fn sleep(&self, dur: Duration)

Block for dur before returning — the passage of real time, injected so waits are deterministic and instant under test.

The release engine’s crates.io index-wait (the multi-crate workspace publish path, crate::release::adapters::cargo) polls between attempts through this method. The default performs a genuine std::thread::sleep, so the production Clock waits for real without implementing anything extra; a deterministic test fake overrides it to advance a virtual clock instead of sleeping, so a bounded-wait loop terminates instantly and without a real delay.

Dyn Compatibility

This trait is dyn compatible.

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