Struct DriverCache 

pub struct DriverCache { /* private fields */ }

An on-disk content-addressed cache for driver pipeline outputs.

Not available on wasm32 targets (no filesystem).

Implementations

impl DriverCache

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

Open (or create) a cache rooted at project_root/.crepus-cache/.

pub fn is_up_to_date(&self, fp: &Fingerprint, output: &str) -> bool

Returns true if output is byte-for-byte identical to the last recorded output for fp. Returns false on any I/O error or cache miss.

pub fn record(&self, fp: &Fingerprint, output: &str)

Record the output hash for fp so future calls to Self::is_up_to_date can detect unchanged output.

Call this after successfully writing the actual output file.
