Implementations

impl<'a> PrimitiveComparer<'a>

fn new( prev: &'a TileDescriptor, curr: &'a TileDescriptor, resource_cache: &'a ResourceCache, spatial_node_comparer: &'a mut SpatialNodeComparer, opacity_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<f32>>, color_bindings: &'a FastHashMap<PropertyBindingId, BindingInfo<ColorU>>, ) -> Self

fn compare_prim( &mut self, prev_desc: &PrimitiveDescriptor, curr_desc: &PrimitiveDescriptor, ) -> PrimitiveCompareResult

Check if two primitive descriptors are the same.
