Trait WallClock 

pub trait WallClock: Send + Sync {
    // Required method
    fn now(&self) -> SystemTime;
}

Provides the current civil time as a SystemTime.

Unlike monotonic time, wall time may move backward after a system clock adjustment and must not be used to measure elapsed durations.

Discarding a sampled wall time is rejected when unused_must_use is denied:

#![deny(unused_must_use)]
use qubit_clock::{StdWallClock, WallClock};

StdWallClock::new().now();

Required Methods

fn now(&self) -> SystemTime

Returns the current wall-clock time.

Returns

The implementor’s current civil-time reading.

Dyn Compatibility

This trait is dyn compatible.

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