}

A trait for a cache of data.

Required Methods

fn put_data( &self, digest: ContentDigest, data: ContentStream, ) -> impl Future<Output = Result<(), Error>> + Send

Puts the data with the given hash into the cache

fn get_data( &self, digest: &ContentDigest, ) -> impl Future<Output = Result<Option<ContentStream>, Error>> + Send

Gets the data with the given hash from the cache. Returns None if the data is not in the cache.

fn put_release( &self, package: &PackageRef, release: &Release, ) -> impl Future<Output = Result<(), Error>> + Send

Puts the release data into the cache.

fn get_release( &self, package: &PackageRef, version: &Version, ) -> impl Future<Output = Result<Option<Release>, Error>> + Send

Gets the release data from the cache. Returns None if the data is not in the cache.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
