Struct ChunkCache 

pub struct ChunkCache { /* private fields */ }

LRU cache for terrain chunks.

Implementations

impl ChunkCache

pub fn new(max_size: usize) -> Self

pub fn with_memory_budget(max_size: usize, budget_bytes: usize) -> Self

pub fn insert(&mut self, coord: ChunkCoord, chunk: TerrainChunk)

Insert or replace a chunk. Evicts LRU if over capacity.

pub fn get(&mut self, coord: ChunkCoord) -> Option<&TerrainChunk>

Get a chunk by coord, updating access time.

pub fn contains(&self, coord: ChunkCoord) -> bool

Check whether the cache contains a coord without updating LRU.

pub fn remove(&mut self, coord: ChunkCoord) -> Option<TerrainChunk>

Remove a specific coord from the cache.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn current_memory_bytes(&self) -> usize
