Trait Clock 

pub trait Clock:
    Send
    + Sync
    + Debug {
    // Required methods
    fn now(&self) -> Instant;
    fn sleep_until(&self, deadline: Instant) -> Sleep;
}

A monotonic clock. Returns tokio::time::Instant so the value slots straight into the existing lease/deadline fields without a type change.

Debug is required because MemoryStore derives it and holds a clock.

Required Methods

fn now(&self) -> Instant

The current instant on this clock’s timeline.

fn sleep_until(&self, deadline: Instant) -> Sleep

Resolve once this clock reaches deadline.

Returns immediately if deadline is already past. On a frozen clock this parks until the test advances past deadline — it must never fall back to real time, or the freeze would leak.

Dyn Compatibility

This trait is dyn compatible.

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