Struct ActiveEffect 

pub struct ActiveEffect<'a> { /* private fields */ }

One effect invocation at one timestamp: timeline time for a timeline transition, composition time for a composition step.

Implementations

impl<'a> ActiveEffect<'a>

pub const fn new(effect: &'a ClipEffect, time: MediaTime) -> Self

The invocation effect sampled at time.

pub fn id(&self) -> &'a str

Stable effect definition identifier.

pub const fn version(&self) -> u32

Exact effect definition version.

pub fn params(&self) -> impl Iterator<Item = (&'a str, EffectParamValue)> + 'a

Every authored parameter, sampled at this timestamp, by name. Parameters the invocation leaves out take their definition defaults.

pub fn param(&self, name: &str) -> Option<EffectParamValue>

One parameter sampled at this timestamp, if the invocation sets it.

pub fn resources( &self, ) -> impl Iterator<Item = (&'a str, &'a EffectResourceId)> + 'a

Named external resources matched against the effect definition.

pub const fn authored(&self) -> &'a ClipEffect

The authored invocation, with its parameters unevaluated.
