pub struct RenderObjectHandle { /* private fields */ }
Expand description
A reference to a RenderObject
with a reference-counted pointer. When the last instance of
a RenderObjectHandle
is dropped, the referenced RenderObject
will be freed from the
RenderObjectSet
. This is returned by register_render_object
on the RenderObjectSet
and may be used to query or mutate the RenderObject
with the get
or get_mut
methods.
