    pub cached_state: MultiCache,
}

Available on crate feature wayland_frontend only.

The state container associated with a surface

This general-purpose container provides 2 main storages:

• the data_map storage has typemap semantics and allows you to associate and access non-buffered data to the surface
• the cached_state storages allows you to associate state to the surface that follows the double-buffering semantics associated with the commit procedure of surfaces, also with typemap-like semantics

See the respective documentation of each container for its usage.

By default, all surfaces have a SurfaceAttributes cached state, and subsurface also have a SubsurfaceCachedState state as well.

Fields

role: Option<&'static str>

The current role of the surface.

If None if the surface has not yet been assigned a role

data_map: UserDataMap

The non-buffered typemap storage of this surface

cached_state: MultiCache

The double-buffered typemap storage of this surface
