Struct CompositionEffectFactory 

pub struct CompositionEffectFactory { /* private fields */ }

Creates the brushes of one effect graph (WinUI Microsoft.UI.Composition.CompositionEffectFactory), made by Compositor::create_effect_factory.

The graph is checked when the factory is made: load_status is Success when the brushes can draw it. A factory whose effect cannot be loaded still makes brushes, which draw nothing.

Deviation (winui-composition.md): WinUI throws from CreateEffectFactory for an effect it cannot load; here the factory is made and reports the failure through its load status and extended error. The factory is not a composition object (no Properties, no animations).

Implementations

impl CompositionEffectFactory

pub fn compositor(&self) -> &Rc<Compositor>

The compositor of the factory.

pub fn create_brush(&self) -> CompositionEffectBrush

CreateBrush: a brush that draws the effect. Its source parameters are bound with set_source_parameter; its animatable properties are entries of its Properties, set to the values of the description.

pub fn load_status(&self) -> CompositionEffectFactoryLoadStatus

LoadStatus: whether the effect was loaded.

pub fn extended_error(&self) -> Option<&CompositionEffectFactoryError>

ExtendedError: why the effect was not loaded; None when it was.
