Struct Cache 

pub struct Cache { /* private fields */ }

A simple filesystem-based cache for audit results.

Implementations

impl Cache

pub fn new(config: &ProjectConfig) -> Result<Self, ForgeGuardError>

Create a new cache instance.

pub fn store<T: Serialize>( &self, key: &str, value: &T, ) -> Result<(), ForgeGuardError>

Store a value in the cache.

pub fn load<T: DeserializeOwned>( &self, key: &str, ) -> Result<Option<T>, ForgeGuardError>

Load a value from the cache.

pub fn has(&self, key: &str) -> bool

Check if a key exists in the cache and is fresh.

pub fn clear(&self) -> Result<(), ForgeGuardError>

Clear all cached entries.

pub fn size(&self) -> u64

Get cache size in bytes.

pub fn file_hash(path: &Path) -> Result<String, ForgeGuardError>

Compute a content hash for incremental file analysis. Returns a hex string of the file’s SHA-256 hash. Used to skip re-analysis of unchanged files.

pub fn is_file_unchanged(&self, file_path: &Path) -> bool

Check if a file has changed since the last analysis using content hashing. Returns true if the file is unchanged (cache hit).

pub fn record_file_hash(&self, file_path: &Path) -> Result<(), ForgeGuardError>

Record a file hash for future incremental analysis. Call this after analyzing a file to mark it as processed.

pub fn filter_changed_files(&self, files: &[PathBuf]) -> Vec<PathBuf>

Filter out files that have not changed since the last analysis. Returns only the files that need (re-)analysis.
