func MustHex ¶

func MustHex(t testing.TB, s string) []byte

MustHex decodes the hexadecimal string s or fails the test immediately.

It accepts testing.TB to support both *testing.T and *testing.B callers without forcing packages to duplicate helper shims.

func OptionalHex ¶

func OptionalHex(t testing.TB, s *string) []byte

OptionalHex decodes the pointed-to string if present, otherwise returning nil.
