Struct CacheStore 

pub struct CacheStore { /* private fields */ }

Cached module information stored on disk.

Implementations

impl CacheStore

pub fn new() -> CacheStore

Create a new empty cache.

pub fn load(cache_dir: &Path) -> Option<CacheStore>

Load cache from disk.

pub fn save(&self, cache_dir: &Path) -> Result<(), String>

Save cache to disk.

pub fn get(&self, path: &Path, content_hash: u64) -> Option<&CachedModule>

Look up a cached module by path and content hash. Returns None if not cached or hash mismatch.

pub fn insert(&mut self, path: &Path, module: CachedModule)

Insert or update a cached module.

pub fn get_by_metadata( &self, path: &Path, mtime_secs: u64, file_size: u64, ) -> Option<&CachedModule>

Fast cache lookup using only file metadata (mtime + size).

If the cached entry has matching mtime and size, the file content almost certainly has not changed, so we can skip reading the file entirely. This turns a cache hit from stat() + read() + hash into just stat().

pub fn get_by_path_only(&self, path: &Path) -> Option<&CachedModule>

Look up a cached module by path only (ignoring hash). Used to check whether a module’s content hash matches without requiring the caller to know the hash upfront.

pub fn retain_paths(&mut self, files: &[DiscoveredFile])

Remove cache entries for files that are no longer in the project. Keeps the cache from growing unboundedly as files are deleted.

pub fn len(&self) -> usize

Number of cached entries.

pub fn is_empty(&self) -> bool

Whether cache is empty.
