Struct wgpu_core::track::buffer::DeviceBufferTracker

pub(crate) struct DeviceBufferTracker {
    current_states: Vec<BufferUses>,
    metadata: ResourceMetadata<Weak<Buffer>>,
    temp: Vec<PendingTransition<BufferUses>>,
}

Stores all buffer state within a device.

Fields

current_states: Vec<BufferUses>

metadata: ResourceMetadata<Weak<Buffer>>

temp: Vec<PendingTransition<BufferUses>>

Implementations

impl DeviceBufferTracker

pub fn new() -> Self

fn tracker_assert_in_bounds(&self, index: usize)

fn allow_index(&mut self, index: usize)

Extend the vectors to let the given index be valid.

pub fn used_resources(&self) -> impl Iterator<Item = Weak<Buffer>> + '_

Returns a list of all buffers tracked.

pub fn insert_single(&mut self, buffer: &Arc<Buffer>, state: BufferUses)

Inserts a single buffer and its state into the resource tracker.

If the resource already exists in the tracker, it will be overwritten.

pub fn set_single( &mut self, buffer: &Arc<Buffer>, state: BufferUses, ) -> Option<PendingTransition<BufferUses>>

Sets the state of a single buffer.

If a transition is needed to get the buffer into the given state, that transition is returned. No more than one transition is needed.

pub fn set_from_tracker_and_drain_transitions<'a, 'b: 'a>( &'a mut self, tracker: &'a BufferTracker, snatch_guard: &'b SnatchGuard<'b>, ) -> impl Iterator<Item = BufferBarrier<'a, dyn DynBuffer>>

Sets the given state for all buffers in the given tracker.

If a transition is needed to get the buffers into the needed state, those transitions are returned.
