Struct TrackBuilder 

pub struct TrackBuilder { /* private fields */ }

Fluent scheduler with deferred diagnostics and immediate try_* alternatives. The requested cursor is not repeatedly rounded: each boundary is snapped once.

Implementations

impl TrackBuilder

pub fn push(self, scene: impl Scene + 'static) -> Self

Appends a finite scene, retaining invalid input for validate().

pub fn scene<Output: IntoSceneOutput + 'static>( self, duration: Duration, build: impl Fn(&SceneContext<'_>) -> Output + Send + Sync + 'static, ) -> Self

Appends a finite authoring callback accepting drawables or Result outputs.

pub fn transition( self, effect: impl Transition + 'static, duration: Duration, ) -> Self

Adds an adjacent transition, retaining invalid input for validate().

pub fn place(self, start: Time, scene: impl Scene + 'static) -> Self

Places a scene at absolute ticks, retaining invalid input for validate().

pub fn gap(self, duration: Duration) -> Self

Advances the cursor, retaining invalid input for validate().

pub fn try_transition( self, effect: impl Transition + 'static, duration: Duration, ) -> Result<Self>

Immediately checks and applies one adjacent transition.

pub fn try_place(self, start: Time, scene: impl Scene + 'static) -> Result<Self>

Immediately checks and places one scene.

pub fn try_gap(self, duration: Duration) -> Result<Self>

Immediately checks and advances the cursor.

pub fn try_push(self, scene: impl Scene + 'static) -> Result<Self>

Appends at the requested cursor; finite positive Scene::duration is required.

pub fn cursor(&self) -> Time

Requested append position, before frame alignment.
