    cache_dir: PathBuf,
}

pub fn get(&self, fingerprint: &[u8]) -> Option<AirBundle>

Try to load a cached bundle for the given fingerprint.

Returns None if no cache entry exists or if deserialization fails.

pub fn put(&self, fingerprint: &[u8], bundle: &AirBundle) -> Result<(), Error>

Store a bundle under the given fingerprint.

Creates the cache directory if it does not exist.

Errors

Returns an error if the cache directory cannot be created or the bundle cannot be serialized/written.

pub fn remove(&self, fingerprint: &[u8]) -> Result<bool, Error>

Remove a cached entry for the given fingerprint.
