如何在Golang中将字符串转换为* uint64？

Question

假设有一个字符串保存类型变量的地址，我们可以将此地址解析成这样吗？uint64 *uint64

例如：

i := uint64(23473824)
ip := &i
str := fmt.Sprintf("%v", ip)

u, _ := strconv.ParseUint(str, 0, 64)

u是uint64，该如何从这个值中取出指针?

Answer 1

You can do it with

 ip = (*uint64)(unsafe.Pointer(uintptr(u)))

Albeit I don't know what guarantees Go gives you about the validity of such a pointer, nor can I think of any use case where this code should be used..
