type Source interface {
	// SHA256 returns the expected SHA256 of the tarball.
	SHA256() []byte

	// Open returns a reader with tarballs body.
	//
	// May optionally use the given `tmp` path as a staging file. It's the
	// caller's responsibility to delete it later.
	//
	// The caller should also verify SHA256 of the data it reads matches SHA256().
	Open(ctx context.Context, tmp string) (io.ReadCloser, error)
}

Source indicates how to grab a tarball.

func New

func New(path, sha256hex string) (Source, error)

New initializes a source by validating path format.

`sha256hex` is optional. If given, it indicates the expected digest of the tarball. It will be verified when the tarball is fetched by cache.Cache.
