Use unsafe cast in inline Compose code (#2349)
Regular casts emit calls into Kotlin's isInterface function and ClassCastException-throwing function. We know these are the types, though, and unsafe cast allows eliminating all that inline code.
Example diff:
if ($composer_1.get_inserting_25mlsw_k$()) {
- var tmp = ensureNotNull($composer_1.get_applier_bupu8u_k$());
- var applier = isInterface(tmp, RedwoodApplier) ? tmp : THROW_CCE();
+ var applier = $composer_1.get_applier_bupu8u_k$();
var tmp_0 = $composer_1;
tmp_0.createNode_ahrd54_k$(function () {
- // Inline function 'com.example.redwood.testapp.compose.Button.<anonymous>' call
- var tmp = applier.get_widgetSystem_mxid3w_k$();
- var tmp$ret$0 = (isInterface(tmp, WidgetFactoryOwner) ? tmp : THROW_CCE()).get_TestSchema_txdklg_k$().Button_x3fioi_k$();
- return new WidgetNode(applier, tmp$ret$0);
+ var tmp$ret$6 = applier.get_widgetSystem_mxid3w_k$().get_TestSchema_txdklg_k$().Button_x3fioi_k$();
+ return new WidgetNode(applier, tmp$ret$6);
});
