Struct Clock 

pub struct Clock { /* private fields */ }

A fake-timer handle for a Page.

Cheaply cloneable; all clones share the same page session and controller.

Implementations

impl Clock

pub async fn install(&self, options: Option<ClockInstallOptions>) -> Result<()>

Engage the fake timers: installs the controller over Date, performance.now, and the timer functions, then optionally pins the time. Call this before the code under test schedules any timers.

pub async fn set_fixed_time(&self, time: Option<i64>) -> Result<()>

Pin the virtual clock so Date.now()/new Date()/performance.now() stop advancing. If time is Some(ms), the clock is also moved there first; None fixes it at the current virtual time.

Calling this implicitly installs the controller if it is not present.

pub async fn advance(&self, ms: i64) -> Result<()>

Advance the virtual clock by ms milliseconds, firing every timer that falls due along the way (just like letting real time pass). Mirrors Playwright’s clock.advance.

pub async fn tick(&self, ms: i64) -> Result<()>

Advance the virtual clock by ms milliseconds without firing any timers in between (they remain pending). Mirrors Playwright’s clock.tick short-form (duration only).

pub async fn run_all(&self) -> Result<()>

Run all pending timers (microtasks/timers queued up to “now”) without moving the clock. Mirrors Playwright’s clock.run_all.

pub async fn resume(&self) -> Result<()>

Resume automatic (real) time progression on this page and clear all fakes. Pending fake timers are discarded. Mirrors Playwright’s clock.resume.

pub async fn resume_all(&self) -> Result<()>

Alias for Clock::resume.

Trait Implementations

impl Clone for Clock

fn clone(&self) -> Clock

Returns a duplicate of the value.

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

Performs copy-assignment from source.
