Struct FrameClock 

pub struct FrameClock { /* private fields */ }

A reusable source bound to one window. Capture current() while building a page, then use it from input handlers or other UI-thread code. A closed window cancels all its registrations.

Implementations

impl FrameClock

pub fn current() -> Self

The current page’s window (the initial window outside a page build).

pub fn request(self, cb: impl FnOnce(Frame) + 'static) -> FrameHandle

Run once at the next frame opportunity. Retain the returned handle until delivery; dropping it cancels. Requests made inside a callback run on a subsequent frame.

pub fn subscribe( self, cb: impl FnMut(Frame) -> ControlFlow<()> + 'static, ) -> FrameHandle

Run while the callback returns Continue(()). Break(()) pauses the subscription; resume() can start it again. Drop or cancel() removes it permanently.
