An interface for handling requests.

Provided methods

`fn destroy(&mut self, object: WlSubcompositor)`

unbind from the subcompositor interface

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wl_subsurface objects included.

This is a destructor, you cannot send requests to this object any longer once this method is called.

`fn get_subsurface( &mut self, object: WlSubcompositor, id: NewResource<WlSubsurface>, surface: WlSurface, parent: WlSurface )`

give a surface the role sub-surface

Create a sub-surface interface for the given surface, and associate it with the given parent surface. This turns a plain wl_surface into a sub-surface.

The to-be sub-surface must not already have another role, and it must not have an existing wl_subsurface object. Otherwise a protocol error is raised.

Adding sub-surfaces to a parent is a double-buffered operation on the parent (see wl_surface.commit). The effect of adding a sub-surface becomes visible on the next time the state of the parent surface is applied.

This request modifies the behaviour of wl_surface.commit request on the sub-surface, see the documentation on wl_subsurface interface.
