Functions

func OpenOrCreate

func OpenOrCreate(path string) (*cacherImpl, error)

OpenOrCreate expects a directory cache with populated indicies for each store or for no directory to exist. If a directory doesn't exist, the function will attempt to create one. Any non-indexed directories within will cause an error to be returned. A valid Cacher will be returned if nil error is returned.

Types

type Cacher

type Cacher interface {
	// Cache a single binary artifact using a namespace and version located at path
	Cache(namespace, version, path string) error
	// Get the path for an already cached binary if one exists. An error will
	// be returned for any case that causes the Cacher to not provide a valid path
	Get(namespace, version string) (string, error)
}

Cacher is used by the builder package to copy the binary of expensive builds.
