Struct CacheManager 

pub struct CacheManager { /* private fields */ }

SHA-256 content-hash deduplication cache backed by SessionStore.

Implementations

impl CacheManager

pub fn new(store: SessionStore, max_size_bytes: u64) -> Self

pub fn get_or_compress( &self, _path: &Path, content: &[u8], pipeline: &CompressionPipeline, ) -> Result<CacheResult>

Look up content in the cache.

• On dedup: return CacheResult::Dedup with a compact reference token.
• On fresh: compress via pipeline, persist to store, return CacheResult::Fresh.

pub fn invalidate(&self, path: &Path) -> Result<()>

Invalidate the cache entry for path if its current content is known.

Reads the file at path, computes its hash, and removes the matching entry from the store. If the file does not exist the call is a no-op.

pub fn evict_lru(&self) -> Result<u64>

Evict least-recently-used entries until total cache size is at or below max_size_bytes.

Returns the number of bytes freed.
