Struct BrowserSession 

pub struct BrowserSession { /* private fields */ }

Lifecycle and clock of a browser view, independent of DOM object ownership.

Implementations

impl BrowserSession

pub fn new(playing: bool) -> Self

Create an inline, visible view with an available graphics context at time zero.

pub fn apply(&mut self, input: SessionInput) -> Result<(), BrowserError>

Apply a lifecycle input; suspension and clock-owner transitions reset the baseline.

Errors

A seek to negative or non-finite time is rejected without changing state.

pub fn playing(&self) -> bool

Whether authored animation is playing, including while temporarily suspended.

pub fn time_seconds(&self) -> f64

Current accepted scene time in seconds.

pub fn active(&self) -> bool

Whether the host may submit a frame in the current lifecycle state.

pub fn frame(&mut self, input: FrameInput) -> Result<FrameTiming, BrowserError>

Validate and advance one frame. The first frame after a transition has zero delta.

Errors

Rejects invalid or backwards timestamps, retaining the previous accepted state.

pub fn sample( &mut self, runtime: &Runtime, input: FrameInput, ) -> Result<Option<Frame>, BrowserError>

Sample an SDK scene using this view’s clock, or return None while suspended.

Errors

Invalid timestamps or rejected SDK frames leave the accepted clock unchanged.

Trait Implementations

impl Clone for BrowserSession

fn clone(&self) -> BrowserSession

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BrowserSession

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
