Types

type OverlayFS

type OverlayFS struct {
	// contains filtered or unexported fields
}

func NewOverlayFS

func NewOverlayFS(root, over fs.FS) *OverlayFS

NewOverlayFS creates a filesystem that overlays the provided overlay over the base root filesystem. Files present in the overlay take precedence over files in the root.

func (*OverlayFS) Open

func (f *OverlayFS) Open(name string) (fs.File, error)

type UserAgentTransport

type UserAgentTransport struct {
	// contains filtered or unexported fields
}

func NewUserAgentTransport

func NewUserAgentTransport(rt http.RoundTripper) *UserAgentTransport

NewUserAgentTransport returns a transport that sets a default User-Agent header for all requests. If rt is nil the http.DefaultTransport is used.

func (*UserAgentTransport) RoundTrip

func (adt *UserAgentTransport) RoundTrip(req *http.Request) (*http.Response, error)
