type Cache interface {
	// Get returns cache for a specified catalog name and version (resolvedRef).
	//
	// Method behaviour is as follows:
	//   - If cache exists, it returns a non-nil fs.FS and nil error
	//   - If cache doesn't exist, it returns nil fs.FS and nil error
	//   - If there was an error during cache population,
	//     it returns nil fs.FS and the error from the cache population.
	//     In other words - cache population errors are also cached.
	Get(catalogName, resolvedRef string) (fs.FS, error)

	// Put writes content from source or from errToCache in the cache backend
	// for a specified catalog name and version (resolvedRef).
	//
	// Method behaviour is as follows:
	//   - If successfully populated cache for catalogName and resolvedRef exists,
	//     errToCache is ignored and existing cache returned with nil error
	//   - If existing cache for catalogName and resolvedRef exists but
	//     is populated with an error, update the cache with either
	//     new content from source or errToCache.
	//   - If cache doesn't exist, populate it with either new content
	//     from source or errToCache.
