go-rtutil

Go runtime / reflect utilities (hacks). You should not use these without deep understanding! (that's probably a bold claim about my own undstanding...)

So yeah, here be dragons and all that.

Functions

func GetRuntimeType 

func GetRuntimeType(t reflect.Type) unsafe.Pointer

GetRuntimeType will fetch a pointer for the runtime._type value of the originating object this reflect.Type represents. This is possible because the reflect package returns the value of an interface{}'s Eface.Type cast as their copy of runtime._type. So the Eface.Data value for this reflected type will be the underlying runtime type this was from.

Types

type Eface 

type Eface struct {
	// Type is a pointer to the runtime._type.
	Type unsafe.Pointer

	// Value is a pointer to the actual data.
	Value unsafe.Pointer
}

Eface (empty interface) is the header for an interface{} value.

func ToEface 

func ToEface(v interface{}) *Eface

ToEface will return the Eface header for given interface{} value.
