inline

Create a new configuration for a snapping layer.

snapper = QgsMapCanvasSnappingUtils(mapCanvas)
snapping_layer1 = QgsSnappingUtils.LayerConfig(layer1, QgsPointLocator.Vertex, 10, Qgis::MapToolUnit::Pixels)
snapping_layer2 = QgsSnappingUtils.LayerConfig(layer2, QgsPointLocator.Vertex and QgsPointLocator.Edge, 10, Qgis::MapToolUnit::Pixels)
snapper.setLayers([snapping_layer1, snapping_layer2])
