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, id: BufferId, 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>>

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