Struct LruTileCache 

pub struct LruTileCache { /* private fields */ }

LRU cache for GPU buffers

Manages a fixed-capacity cache of GPU buffers with LRU eviction policy. When capacity is reached, least recently used tile is evicted.

Implementations

impl LruTileCache

pub fn new(capacity: usize) -> Self

Create new LRU cache with given capacity

pub fn get(&mut self, tile_id: usize) -> Option<&Buffer>

Get buffer from cache (marks as recently used)

pub fn insert(&mut self, tile_id: usize, buffer: Buffer) -> Option<usize>

Insert buffer into cache (may evict LRU tile)

Returns evicted tile ID if eviction occurred

pub fn contains(&self, tile_id: usize) -> bool

Check if tile is in cache

pub fn len(&self) -> usize

Get current cache size

pub fn is_empty(&self) -> bool

Check if cache is empty

pub fn clear(&mut self)

Clear all cached buffers

pub fn capacity(&self) -> usize

Get cache hit rate statistics
