Struct LodGpuCache 

pub struct LodGpuCache { /* private fields */ }

Backend-neutral GPU residency ledger with deterministic LRU eviction.

Implementations

impl LodGpuCache

pub fn try_new(budgets: LodBudgets) -> LodResult<Self>

Creates an empty bounded cache.

pub fn resident_ids(&self) -> BTreeSet<NodeId>

Current resident IDs.

pub fn resident(&self, id: NodeId) -> Option<&ResidentNode>

Finds a resident.

pub fn touch(&mut self, id: NodeId, generation: u64) -> LodResult<()>

Marks a resident as used by generation.

pub fn admit( &mut self, id: NodeId, point_count: u64, gpu_bytes: u64, generation: u64, protected: &BTreeSet<NodeId>, ) -> LodResult<GpuCacheReceipt>

Admits a completed explicit upload, evicting only unprotected LRU nodes.

Failure leaves the cache unchanged.

pub fn remove(&mut self, id: NodeId) -> Option<ResidentNode>

Explicitly removes a node.
