[Experimental] Information about a compositing layer.

Fields

layer_id: LayerId<'a>

The unique id for this layer.

parent_layer_id: Option<LayerId<'a>>

The id of parent (not present for root).

backend_node_id: Option<BackendNodeId>

The backend id for the node associated with this layer.

offset_x: f64

Offset from parent layer, X coordinate.

offset_y: f64

Offset from parent layer, Y coordinate.

width: f64

Layer width.

height: f64

Layer height.

transform: Option<[f64; 16]>

Transformation matrix for layer, default is identity matrix

anchor_x: Option<f64>

Transform anchor point X, absent if no transform specified

anchor_y: Option<f64>

Transform anchor point Y, absent if no transform specified

anchor_z: Option<f64>

Transform anchor point Z, absent if no transform specified

paint_count: i32

Indicates how many time this layer has painted.

draws_content: bool

Indicates whether this layer hosts any content, rather than being used for transform/scrolling purposes only.

invisible: Option<bool>

Set if layer is not visible.

scroll_rects: Option<Vec<ScrollRect>>

Rectangles scrolling on main thread only.

sticky_position_constraint: Option<StickyPositionConstraint<'a>>

Sticky position constraint information

Trait Implementations

impl<'a> Clone for Layer<'a>

fn clone(&self) -> Layer<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Layer<'a>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for Layer<'a>

fn eq(&self, __arg_0: &Layer<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Layer<'a>) -> bool

This method tests for !=.
