In Go, you can pass functions as parameters like callFunction(fn func)
. For example:
package main
import "fmt"
func example() {
fmt.Println("hello from example")
}
func callFunction(fn func) {
fn()
}
func main() {
callFunction(example)
}
But is it possible to call a function when it's a member of a struct? The following code would fail, but gives you an example of what I'm talking about:
package main
import "fmt"
type Example struct {
x int
y int
}
var example Example
func (e Example) StructFunction() {
fmt.Println("hello from example")
}
func callFunction(fn func) {
fn()
}
func main() {
callFunction(example.StructFunction)
}
(I know what I'm trying to do in that example is a little odd. The exact problem I have doesn't scale down to a simple example very well, but that's the essence of my problem. However I'm also intrigued about this from an academic perspective)
