How to cast custom type slice to primitive slice in Golang?

Question

type TCustomIntType int

func aFunc() {
    var fails []TCustomIntType = []TCustomIntType([]int{})
}

I got:

cannot convert []int literal (type []int) to type []TCustomIntType

How to fix it? Do I have to write a convert func manually?

Note that you can't cast _anything_ in Go. Go doesn't do type casting, only type conversion. — Jonathan Hall, Dec 29 '17 at 10:10

Yes, you have to copy it manually with a for loop.
