Struct CustomNode 

pub struct CustomNode {
    pub debug_tag: String,
    pub lowerer: Option<Arc<dyn LowerDyn>>,
}

An application-defined node with custom lowering logic.

CustomNode is the escape hatch for widgets that cannot be expressed with the built-in primitives. Provide a LowerDyn implementation to emit arbitrary fission-ir operations.

Example

let custom = CustomNode {
    debug_tag: "MyCanvasWidget".to_string(),
    lowerer: Some(Arc::new(MyCanvasLowerer)),
};
Node::Custom(custom)

Fields

debug_tag: String

Human-readable name for debugging and diagnostics.

lowerer: Option<Arc<dyn LowerDyn>>

The lowering implementation (skipped during serialisation).
