Is there a way to have custom typecasting in GoLang?

I know there is typecasting in GoLang, such as:

type long int64;
type ulong uint64;

var l long = 39486;
var i16 = int64(l);
var ui16 = uint64(i16);

fmt.Println( string([]byte {100, 150, 125, 68, 66}) );

I know there is typecasting in GoLang, such as:

type long int64;
type ulong uint64;

var l long = 39486;
var i16 = int64(l);
var ui16 = uint64(i16);

fmt.Println( string([]byte {100, 150, 125, 68, 66}) );

But is there a way to add them to interface/struct types?

type IJType interface {/* ... */}

type JByte struct {/* Implements IJType */}

Is there a way I could make a constructor, like in the following?

var j JByte = JByte(255 /*byte*/); // -> JByte(byte) -> JByte {/* ... */}
byte(j); // 255.
