/// `ReturnType` describes what value type the kernel has returned.
// ReturnType is not an enum so that it can be converted from a u32 for free.
// TODO: derive(Debug) is currently only enabled for test builds, which is
// necessary so it can be used in assert_eq!. We should develop a lighter-weight
// Debug implementation and see if it is small enough to enable on non-Debug
// builds.
