Trait BaseEffectExt

pub trait BaseEffectExt: IsA<BaseEffect> + 'static {
    // Provided methods
    fn is_time_effect(&self) -> bool { ... }
    fn register_time_property(&self, child_property_name: &str) -> bool { ... }
}

Trait containing all BaseEffect methods.

BaseEffect, Effect

Provided Methods

fn is_time_effect(&self) -> bool

Get whether the effect is considered a time effect or not. An effect with registered time properties or set translation functions is considered a time effect.

Returns

true if self is considered a time effect.

fn register_time_property(&self, child_property_name: &str) -> bool

Register a child property of the effect as a property that, when set, can change the timing of its input data. The child property should be specified as in TimelineElementExt::lookup_child().

You should also set the corresponding time translation using ges_base_effect_set_time_translation_funcs().

Note that self must not be part of a clip, nor can it have has-internal-source set to true.

child_property_name

The name of the child property to register as a time property

Returns

true if the child property was found and newly registered.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
