Struct AnyContainerLayer 

pub struct AnyContainerLayer { /* private fields */ }

Erased ContainerLayer.

Implementations

impl AnyContainerLayer

pub fn id(self) -> HandleId

pub fn as_offset_layer(self) -> Option<AnyOffsetLayer>

Dart’s layer as OffsetLayer, as an Option.

pub fn first_child(self, app: &App) -> Option<AnyLayer>

The first composited layer in this layer’s child list.

pub fn last_child(self, app: &App) -> Option<AnyLayer>

The last composited layer in this layer’s child list.

pub fn has_children(self, app: &App) -> bool

Returns whether this layer has at least one child layer.

pub fn build_scene(self, app: &mut App, builder: SceneBuilder) -> Scene

Consider this layer as the root and build a scene (a tree of layers) in the engine.

pub fn append(self, app: &mut App, child: AnyLayer)

Adds the given layer to the end of this layer’s child list.

pub fn redepth_child(self, app: &mut App, child: AnyLayer)

Adjust the depth of the given child to be greater than this node’s own depth.

Only call this method from overrides of Layer::redepth_children.

pub fn remove_all_children(self, app: &mut App)

Removes all of this layer’s children from its child list.

pub fn add_children_to_scene(self, app: &mut App, builder: &mut SceneBuilder)

Uploads all of this layer’s children to the engine.

This method is typically used by add_to_scene to insert the children into the scene. Subclasses of ContainerLayer typically override add_to_scene to apply effects to the scene using the SceneBuilder API, then insert their children using add_children_to_scene, then reverse the aforementioned effects before returning from add_to_scene.

pub fn apply_transform( self, app: &App, child: Option<AnyLayer>, transform: &mut Matrix4, )

See ContainerLayer::apply_transform.

pub fn depth_first_iterate_children(self, app: &App) -> Vec<AnyLayer>

Returns the descendants of this layer in depth first order.
