wl-proxy 0.1.2

//! lease device
//!
//! This protocol is used by Wayland compositors which act as Direct
//! Rendering Manager (DRM) masters to lease DRM resources to Wayland
//! clients.
//!
//! The compositor will advertise one wp_drm_lease_device_v1 global for each
//! DRM node. Some time after a client binds to the wp_drm_lease_device_v1
//! global, the compositor will send a drm_fd event followed by zero, one or
//! more connector events. After all currently available connectors have been
//! sent, the compositor will send a wp_drm_lease_device_v1.done event.
//!
//! When the list of connectors available for lease changes the compositor
//! will send wp_drm_lease_device_v1.connector events for added connectors and
//! wp_drm_lease_connector_v1.withdrawn events for removed connectors,
//! followed by a wp_drm_lease_device_v1.done event.
//!
//! The compositor will indicate when a device is gone by removing the global
//! via a wl_registry.global_remove event. Upon receiving this event, the
//! client should destroy any matching wp_drm_lease_device_v1 object.
//!
//! To destroy a wp_drm_lease_device_v1 object, the client must first issue
//! a release request. Upon receiving this request, the compositor will
//! immediately send a released event and destroy the object. The client must
//! continue to process and discard drm_fd and connector events until it
//! receives the released event. Upon receiving the released event, the
//! client can safely cleanup any client-side resources.
//!
//! Warning! The protocol described in this file is currently in the testing
//! phase. Backward compatible changes may be added together with the
//! corresponding interface version bump. Backward incompatible changes can
//! only be done by creating a new major version of the extension.
