Struct MockClock 

pub struct MockClock { /* private fields */ }

Mock clock for testing with controllable time.

The mock clock starts at a fixed or specified time and only advances when explicitly told to via advance().

Implementations

impl MockClock

pub fn new() -> Self

Create a mock clock starting at time zero.

pub fn fixed(iso_time: &str) -> Self

Create a mock clock fixed at the specified ISO 8601 time.

Example

use xerv_core::testing::{MockClock, ClockProvider};

let clock = MockClock::fixed("2024-01-15T10:30:00Z");
assert!(clock.system_time_millis() > 0);

pub fn at_now() -> Self

Create a mock clock starting at the current system time.

pub fn current_nanos(&self) -> u64

Get the current monotonic time in nanoseconds.

Trait Implementations

impl ClockProvider for MockClock

fn now(&self) -> u64

Get a monotonic instant (for measuring durations).

fn system_time_millis(&self) -> u64

Get the current system time as milliseconds since UNIX epoch.

fn sleep( &self, duration: Duration, ) -> Pin<Box<dyn Future<Output = ()> + Send + '_>>

Sleep for the specified duration.

fn advance(&self, duration: Duration)

Advance time by the specified duration (mock-only operation).

fn is_mock(&self) -> bool

Check if this is a mock clock.

impl Default for MockClock

fn default() -> Self

Returns the “default value” for a type.
