Struct ExtractionCache 

pub struct ExtractionCache { /* private fields */ }

Cache of per-file extraction results keyed by path.

IDs inside the cached extractions stay valid. New extractions must start above ExtractionCache::max_symbol_id.

Implementations

impl ExtractionCache

pub fn new() -> Self

Create an empty cache.

pub fn get(&self, path: &Path) -> Option<&Arc<FileExtraction>>

Cached extraction for a path.

pub fn fingerprint_of(&self, path: &Path) -> Option<Fingerprint>

Cached fingerprint for a path.

pub fn max_symbol_id(&self) -> u32

Find the highest raw symbol ID allocated across all cached files.

pub fn update( &mut self, path: PathBuf, fp: Fingerprint, extraction: Arc<FileExtraction>, )

Update or insert a file’s fingerprint and shared extraction.

pub fn remove(&mut self, path: &Path)

Remove a file from the extraction and fingerprint cache.

pub fn len(&self) -> usize

Number of cached files.

pub fn is_empty(&self) -> bool

True when no file is cached.

pub fn paths(&self) -> impl Iterator<Item = &PathBuf>

Iterate over cached paths.
