任何人都可以帮助我吗？将 uint64 转换为 int64 请

//fmt.Println(int64(18446744073709551615)) 
//constant 18446744073709551615 overflows int64 

var x uint64 = 18446744073709551615
var y int64 = int64(x)
fmt.Println(y) //-1 

//just like(c)signed long long
//anyone can help me pls!
//How can I using like this?

func BytesToInt(b []byte) int {
    bytesBuffer := bytes.NewBuffer(b)
    var tmp int32
    binary.Read(bytesBuffer, binary.BigEndian, &tmp)
    return int(tmp)
}
