Trait Clock 

pub trait Clock:
    Send
    + Sync
    + 'static {
    // Required method
    fn now(&self) -> DateTime<Utc>;
}

A source of the current time.

The guard never calls Utc::now directly, so tests (and simulations) can drive time with ManualClock. Any Fn() -> DateTime<Utc> closure is also a clock.

Required Methods

fn now(&self) -> DateTime<Utc>

The current instant.

Dyn Compatibility

This trait is dyn compatible.

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