Struct MockClock 

pub struct MockClock { /* private fields */ }

Mock clock for testing with interior mutability.

Uses AtomicU64 so the clock can be modified while the generator holds a reference to it.

Examples

use nulid::generator::{MockClock, Clock};
use core::time::Duration;

let clock = MockClock::new(1_000_000_000);
assert_eq!(clock.get(), 1_000_000_000);

clock.advance(Duration::from_millis(100));
assert_eq!(clock.get(), 1_100_000_000);

clock.regress(Duration::from_millis(50));
assert_eq!(clock.get(), 1_050_000_000);

Implementations

impl MockClock

pub const fn new(initial_nanos: u64) -> Self

Creates a new mock clock with the given initial time.

pub fn get(&self) -> u64

Gets the current time in nanoseconds.

pub fn set(&self, nanos: u64)

Sets the clock to a specific time.

pub fn advance(&self, duration: Duration)

Advances the clock by the given duration.

pub fn regress(&self, duration: Duration)

Regresses the clock by the given duration (simulates clock going backward).

Trait Implementations

impl Clock for &MockClock

fn now_nanos(&self) -> Result<u128>

Returns current time in nanoseconds since Unix epoch.

impl Clock for MockClock

fn now_nanos(&self) -> Result<u128>

Returns current time in nanoseconds since Unix epoch.

impl Debug for MockClock

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

Formats the value using the given formatter.

impl Default for MockClock

fn default() -> Self

Returns the “default value” for a type.
