Struct MockClock 

pub struct MockClock { /* private fields */ }

Deterministic mock clock for testing. Time advances only when explicitly set or stepped.

Implementations

impl MockClock

pub fn new(initial_time: NtpTimestamp) -> Self

pub fn set_time(&self, time: NtpTimestamp)

Set the current time directly.

pub fn advance(&self, nanos: i64)

Advance time by a duration (in nanoseconds).

pub fn set_adjustable(&self, adjustable: bool)

Set whether this clock can be adjusted.

pub fn get_frequency(&self) -> f64

Get current frequency offset.

Trait Implementations

impl Clock for MockClock

fn now(&self) -> Result<NtpTimestamp, ClockError>

Read current time from this clock.

fn step(&self, offset: NtpDuration) -> Result<(), ClockError>

Apply a step adjustment (instant offset). Requires privilege.

fn adjust_frequency(&self, ppm: f64) -> Result<(), ClockError>

Apply a slew adjustment (frequency change in PPM). Requires privilege.

fn frequency_offset(&self) -> Result<f64, ClockError>

Read current frequency offset in PPM.

fn resolution(&self) -> NtpDuration

Get clock resolution as a duration.

fn max_frequency_adjustment(&self) -> f64

Maximum allowed frequency adjustment in PPM.

fn is_adjustable(&self) -> bool

Whether this clock supports discipline (has CAP_SYS_TIME or equivalent).

impl Clone for MockClock

fn clone(&self) -> MockClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.
