Constants

const (
	// UnsafeDisabled is a build-time constant which specifies whether or
	// not access to the unsafe package is available.
	UnsafeDisabled = false
)

Variables

var GetInterface = func(val reflect.Value, force bool) (interface{}, bool) {
	if !val.IsValid() {
		return nil, true
	}

	if val.CanInterface() {
		return val.Interface(), true
	}

	if force {
		val = unsafeReflectValue(val)
		if val.CanInterface() {
			return val.Interface(), true
		}
	}

	copyVal, ok := CopyValue(val)
	if ok && copyVal.CanInterface() {
		return copyVal.Interface(), true
	}

	return nil, false
}

GetInterface does its best to return the data behind val. If force is true, it tries to bypass golang protections using the unsafe package.

It returns (nil, false) if the data behind val can not be retrieved as an interface{} (aka. struct private + non-copyable field).

Functions

func CopyValue

func CopyValue(val reflect.Value) (reflect.Value, bool)

CopyValue does its best to copy val in a new reflect.Value instance.

func MustGetInterface

func MustGetInterface(val reflect.Value) interface{}

MustGetInterface does its best to return the data behind val. If it fails (struct private + non-copyable field), it panics.
