Struct FrameClock 

pub struct FrameClock { /* private fields */ }

Shared frame clock owned by the runtime.

Every view animation samples this clock instead of calling Instant::now() on its own. That gives one coherent timestamp per frame, deterministic tests, global speed control and reduced-motion support.

Implementations

impl FrameClock

pub fn new() -> Self

pub fn now(&self) -> Instant

Current animation time. This is not affected by wall-clock jumps.

pub fn elapsed(&self) -> Duration

pub fn elapsed_secs(&self) -> f32

pub fn dt(&self) -> Duration

pub fn dt_secs(&self) -> f32

pub fn frame(&self) -> u64

pub fn speed(&self) -> f32

pub fn set_speed(&mut self, speed: f32)

pub fn reduced_motion(&self) -> bool

pub fn set_reduced_motion(&mut self, reduced: bool)

pub fn is_manual(&self) -> bool

pub fn set_manual(&mut self, manual: bool)

pub fn advance(&mut self)

Advance from the wall clock. Manual clocks do not advance implicitly.

pub fn advance_by(&mut self, dt: Duration)

Advance by an explicit duration. Used by tests and deterministic hosts.

pub fn reset(&mut self)
