Function getPkgPath

errbase/encode.go:276–288

getPkgPath extract the package path for a Go type. We'll do some extra work for typical types that did not get a name, for example *E has the package path of E.

(t reflect.Type)

// extra work for typical types that did not get a name, for example
// *E has the package path of E.
func getPkgPath(t reflect.Type) string {
	pkgPath := t.PkgPath()
	if pkgPath != "" {
		return pkgPath
	}
	// Try harder.
	switch t.Kind() {
	case reflect.Array, reflect.Chan, reflect.Map, reflect.Ptr, reflect.Slice:
		return getPkgPath(t.Elem())
	}
	// Nothing to report.
	return ""
}

// TypeKey identifies an error for the purpose of looking up decoders.
// It is equivalent to the "family name" in ErrorTypeMarker.
