Functions

func DigestAndSize

func DigestAndSize(r io.Reader) (digest.Digest, int64, error)

DigestAndSize returns the digest and size of the given Reader.

func EmbeddedLinuxImage

func EmbeddedLinuxImage() (io.ReadCloser, error)

EmbeddedLinuxImage returns a reader pointing to an embedded linux image with the following assumptions: - if the current GOOS is linux, returns the current binary. - if the current GOOS is darwin, and current binary size is larger than what Mach-O reports, returns a reader to the current binary offset by the size of the darwin binary. - returns ErrNoEmbeddedImage if

• if the current GOOS is not darwin
• if the current GOOS is darwin, but there's no embedding.

func ExecPath

func ExecPath() (string, error)

ExecPath returns an absolute path to the executable of the current running process.
