Question

Dealing with go’s funcs I discovered that one can’t force the compiler to control whether I pass a value or pointer-to-value argument when using ‘generic’ interface{} type.

func f(o interface{}) {
...
}

The most obvious solution is to use the following modification:

func f(o *interface{}) {
...
}

Although this is successfully compiled I didn’t find this step right. So, is there any means to state that I want to pass any pointer?

Answer 1

No. At compile time, interface{}, the empty interface, is any type.

all types implement the empty
interface: interface{} Interface
