Trait Clock 

pub trait Clock {
    // Required method
    fn now(&self) -> Option<Timestamp>;
}

A service to get the current Timestamp.

Required Methods

fn now(&self) -> Option<Timestamp>

Read the current Timestamp.

This method may return None if the clock couldn’t be read for any reason. That may be because the clock doesn’t actually supporting reading now, time moving backwards, or any other reason that could result in an inaccurate reading.

Dyn Compatibility

This trait is dyn compatible.

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