Implementations

impl Cache

pub fn new(root: PathBuf) -> Self

Construct an isolated cache location without modifying existing files.

pub fn revision(&self) -> u64

Retire disk reads captured before an explicit cache removal.

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

Remove only this source’s disposable catalogue and artwork, never personal stores.

pub fn load(&self) -> Result<Option<Value>, String>

A missing cache is distinct from an unreadable or incompatible cache. Old public caches lose private policy metadata atomically; supervised projections remain process-only.

pub fn save(&self, snapshot: Value) -> Result<Value, String>

Atomically publish a complete library snapshot after explicit synchronization.

pub fn image( &self, snapshot: &Value, reference: &str, kind: &str, ) -> Result<Option<Vec<u8>>, String>

Read already synchronized art; missing art may then be requested explicitly.

pub fn save_image( &self, snapshot: &Value, reference: &str, kind: &str, bytes: &[u8], ) -> Result<(), String>

Share immutable catalogue art across accounts of the same authority and catalogue version. The native caller must separately admit the reference through the active account projection.

Trait Implementations

impl Clone for Cache

fn clone(&self) -> Cache

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
