Struct wgpu_core::init_tracker::InitTracker

pub(crate) struct InitTracker<Idx: Ord + Copy + Default> {
    uninitialized_ranges: SmallVec<[Range<Idx>; 1]>,
}

Tracks initialization status of a linear range from 0..size

Fields

uninitialized_ranges: SmallVec<[Range<Idx>; 1]>

Non-overlapping list of all uninitialized ranges, sorted by range end.

Implementations

impl InitTracker<BufferAddress>

pub(crate) fn check_action( &self, action: &BufferInitTrackerAction, ) -> Option<BufferInitTrackerAction>

Checks if an action has/requires any effect on the initialization status and shrinks its range if possible.

pub(crate) fn create_action( &self, buffer: &Arc<Buffer>, query_range: Range<BufferAddress>, kind: MemoryInitKind, ) -> Option<BufferInitTrackerAction>

Creates an action if it would have any effect on the initialization status and shrinks the range if possible.

impl<Idx> InitTracker<Idx>

where Idx: Debug + Ord + Copy + Default,

pub(crate) fn new(size: Idx) -> Self

pub(crate) fn check(&self, query_range: Range<Idx>) -> Option<Range<Idx>>

Checks for uninitialized ranges within a given query range.

If query_range includes any uninitialized portions of this init tracker’s resource, return the smallest subrange of query_range that covers all uninitialized regions.

The returned range may be larger than necessary, to keep this function O(log n).

pub(crate) fn uninitialized( &mut self, drain_range: Range<Idx>, ) -> UninitializedIter<'_, Idx>

pub(crate) fn drain( &mut self, drain_range: Range<Idx>, ) -> InitTrackerDrain<'_, Idx>

impl InitTracker<u32>

pub(crate) fn discard(&mut self, pos: u32)

Trait Implementations

impl<Idx: Clone + Ord + Copy + Default> Clone for InitTracker<Idx>

fn clone(&self) -> InitTracker<Idx>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Idx: Debug + Ord + Copy + Default> Debug for InitTracker<Idx>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
