Required Methods

fn writer(&self, key: &StorageKey) -> Pending<'_, Box<dyn Writer>>

fn reader(&self, key: &StorageKey) -> Pending<'_, Option<Box<dyn Reader>>>

fn delete(&self, key: &StorageKey) -> Pending<'_, ()>

Deleting a key that holds nothing succeeds.

fn exists(&self, key: &StorageKey) -> Pending<'_, bool>

fn download_url(&self, link: &DownloadLink<'_>) -> Result<String>

Provided Methods

fn served(&self, _path_and_query: &str, _now: Timestamp) -> Option<Served>
