Struct ProjectCache 

pub struct ProjectCache { /* private fields */ }

Unified project cache: parse results + findings + symbol summaries. Facade over three cache layers (models, symbols, findings) plus the meta bookkeeping they share. Method count ≥ 10 is structural, not a smell — each layer exposes get/put atop the layered read/write helpers.

Implementations

impl ProjectCache

pub fn open(project_root: &Path, env_hash: u64) -> Self

Open or create a cache for the given project root.

pub fn check_file(&self, rel_path: &str, path: &Path) -> FileStatus

Check if a file is unchanged (mtime + size match). Returns (is_unchanged, content_hash) — hash is 0 if unchanged and not yet computed.

pub fn get_model(&mut self, chash: u64) -> Option<SourceModel>

Get cached SourceModel: L1 memory → L2 disk.

pub fn put_model(&mut self, chash: u64, model: &SourceModel)

Store a SourceModel in L1 + L2.

pub fn get_symbols(&mut self, chash: u64) -> Option<SymbolIndex>

Get a cached SymbolIndex: L1 memory → L2 disk. Fast path for cha deps, LSP workspace-symbols and any other consumer that only needs structural information (names, relations, positions) without per-function-body analyse data.

pub fn put_symbols(&mut self, chash: u64, idx: &SymbolIndex)

Store a SymbolIndex in L1 + L2. Called alongside put_model so both caches stay in lockstep.

pub fn get_findings(&self, chash: u64) -> Option<Vec<Finding>>

Get cached findings for a file.

pub fn put_findings(&mut self, chash: u64, findings: &[Finding])

Store findings for a file.

pub fn update_file_entry( &mut self, rel_path: String, path: &Path, chash: u64, imports: Vec<String>, )

Update file metadata after processing.

pub fn get_imports(&self, rel_path: &str) -> Option<&[String]>

Get cached imports for a file (from meta, no disk I/O).

pub fn flush(&self)

Flush metadata to disk and clean up orphan cache files.
