Struct ComponentNodeMetaData

pub struct ComponentNodeMetaData {
    pub computed_data: Option<ComputedData>,
    pub rel_position: Option<PxPosition>,
    pub abs_position: Option<PxPosition>,
    /* private fields */
}

Contains metadata of the component node.

Fields

computed_data: Option<ComputedData>

The computed data (size) of the node. None if the node is not computed yet.

rel_position: Option<PxPosition>

The node’s start position, relative to its parent. None if the node is not placed yet.

abs_position: Option<PxPosition>

The node’s start position, relative to the root window. This will be computed during drawing command’s generation. None if the node is not drawn yet.

Implementations

impl ComponentNodeMetaData

pub fn none() -> Self

Creates a new ComponentNodeMetaData with default values.

pub fn push_draw_command(&mut self, command: impl DrawCommand + 'static)

Pushes a draw command to the node’s metadata.

Draw commands are responsible for rendering visual content (shapes, text, images). This method wraps the command in the unified Command::Draw variant and adds it to the command queue. Commands are executed in the order they are added.

Example

metadata.push_draw_command(ShapeCommand::Rect {
    color: [1.0, 0.0, 0.0, 1.0],
    corner_radius: 8.0,
    shadow: None,
});

pub fn push_compute_command(&mut self, command: impl ComputeCommand + 'static)

Pushes a compute command to the node’s metadata.

Compute commands perform GPU computation tasks (post-processing effects, complex calculations). This method wraps the command in the unified Command::Compute variant and adds it to the command queue.

Example

metadata.push_compute_command(BlurCommand {
    radius: 5.0,
    sigma: 2.0,
});

Trait Implementations

impl Default for ComponentNodeMetaData

fn default() -> ComponentNodeMetaData

Returns the “default value” for a type.
