Struct SystemClock 

pub struct SystemClock;

A clock implementation that uses the system’s wall clock time.

This is a zero-sized type (ZST) with no runtime overhead. It directly queries the system for the current time whenever millis() or time() is called.

Note

The time returned by this clock is subject to system time adjustments, such as NTP synchronization or manual changes. For monotonic time measurements, use MonotonicClock instead.

Thread Safety

This type is completely thread-safe as it has no mutable state.

Examples

use prism3_clock::{Clock, SystemClock};

let clock = SystemClock::new();
let timestamp = clock.millis();
let time = clock.time();
println!("Current system time: {}", time);

impl Clone for SystemClock

fn clone(&self) -> SystemClock

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SystemClock

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SystemClock

fn default() -> SystemClock

Returns the “default value” for a type.
