Struct SlotRewriteQueue 

pub struct SlotRewriteQueue { /* private fields */ }

Defers draw-slot rewrites until every in-flight frame has retired.

Implementations

impl SlotRewriteQueue

pub fn new(frames_in_flight: usize) -> Self

A queue sized for frames_in_flight in-flight frames.

pub fn queue(&mut self, slot: usize)

Queue pool slot for rewriting in every per-frame copy. Re-queueing a slot mid-propagation restarts its countdown, so every copy ends on the view the caller swapped in last (the rewrite reads the pool at apply time, not at queue time).

pub fn begin_frame(&mut self) -> Vec<usize>

The slots whose descriptor must be rewritten in the frame copy about to record. Call exactly once per frame, after the frame slot’s fence wait. Entries that have now covered every copy are dropped.

pub fn remove(&mut self, slot: usize)

Drop a queued slot: the caller rewrote every copy itself (e.g. a fallback full rewrite under a device drain).

pub fn is_empty(&self) -> bool

Whether nothing is queued.
