    state: AtomicU8,
}

ObjectData for the WlBuffer

Fields

inner: Arc<SlotInner>

state: AtomicU8

Implementations

impl BufferData

const ACTIVE: u8 = 0u8

Buffer is counted in active_buffers list; will return to INACTIVE on Release.

const INACTIVE: u8 = 1u8

Buffer is not counted in active_buffers list, but also has not been destroyed.

const DESTROY_ON_RELEASE: u8 = 2u8

Buffer is counted in active_buffers list; will move to DEAD on Release

const DEAD: u8 = 3u8

Buffer has been destroyed

const RELEASE_SET: u8 = 1u8

Value that is ORed on buffer release to transition to the next state

const DESTROY_SET: u8 = 2u8

Value that is ORed on buffer destroy to transition to the next state

fn record_death(&self)

Call after successfully transitioning the state to DEAD
