Struct MeshCache 

pub struct MeshCache {
    pub capacity: usize,
    /* private fields */
}

LRU mesh cache for terrain chunks.

Evicts least-recently-used chunks when capacity is exceeded.

Fields

capacity: usize

Implementations

impl MeshCache

pub fn new(capacity: usize) -> Self

pub fn insert(&mut self, data: TerrainChunkData)

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

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

Get a reference to a chunk, updating its LRU position.

pub fn peek(&self, coord: ChunkCoord) -> Option<&TerrainChunkData>

Get without updating LRU (read-only peek).

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

Remove a chunk explicitly.

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

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = (&ChunkCoord, &TerrainChunkData)>

Iterate over all loaded chunks.

pub fn evict_unloading(&mut self)

Evict all chunks marked as Unloading.
