func NewBinaryCacheReader ¶
func NewBinaryCacheReader(ctx context.Context, storeURL string) (BinaryCacheReader, error)
NewBinaryCacheReader parses the storeURL and returns the proper store reader for it.
type GCSBinaryCacheStore ¶
type GCSBinaryCacheStore struct {
// contains filtered or unexported fields
}
GCSBinaryCacheStore ...
func NewGCSBinaryCacheStore ¶
NewGCSBinaryCacheStore --
func (GCSBinaryCacheStore) FileExists ¶
FileExists returns true if the file is already in the store. err is used for transient issues like networking errors.
