Enum SceneDuration 

#[non_exhaustive]
pub enum SceneDuration {
    Finite(TimeStamp),
    Indefinite,
}

How long a scene lasts on its own clock.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Finite(TimeStamp)

Fixed-length scene. Rendered linearly start→end; finishes at end and emits no further frames.

Indefinite

Streaming / open-ended. The scene runs forever until an operation explicitly ends it. Used by the RTMP compositor. Seek / rewind are not supported; content is driven forward by wall-clock time + control-plane operations.

Implementations

impl SceneDuration

pub fn end(&self) -> Option<TimeStamp>

Return Some(end) for finite scenes, None for streaming.

pub fn contains(&self, t: TimeStamp) -> bool

Whether a given timestamp is inside the scene.

Trait Implementations

impl Clone for SceneDuration

fn clone(&self) -> SceneDuration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SceneDuration

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

Formats the value using the given formatter.

impl PartialEq for SceneDuration

fn eq(&self, other: &SceneDuration) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
