Struct ChunkCache 

pub struct ChunkCache { /* private fields */ }

LRU cache for decompressed chunks.

Thread-safe via parking_lot::Mutex (non-poisoning). Values are Arc<Vec<u8>> so multiple readers can share the same decompressed chunk data.

Implementations

impl ChunkCache

pub fn new(max_bytes: usize, max_slots: usize) -> Self

Create a new chunk cache.

• max_bytes: maximum total bytes of decompressed data to cache (default 64 MiB)
• max_slots: maximum number of entries (default 521)

pub fn get(&self, key: &ChunkKey) -> Option<Arc<Vec<u8>>>

Get a cached chunk, if present. Promotes the entry in LRU order.

pub fn insert(&self, key: ChunkKey, data: Vec<u8>) -> Arc<Vec<u8>>

Insert a chunk into the cache. Evicts LRU entries if over capacity.

pub fn get_or_insert_with<F>( &self, key: ChunkKey, load: F, ) -> Result<Arc<Vec<u8>>>

where F: FnOnce() -> Result<Vec<u8>>,

Return a cached chunk or compute it once across concurrent callers.

pub fn stats(&self) -> ChunkCacheStats

Return current cache statistics.

Trait Implementations

impl Default for ChunkCache

fn default() -> Self

Returns the “default value” for a type.
