My use case is, I need to have several structs in Go, who will have methods of same signatures and not necessarily have to have all the methods. The following code describes the requirements and also represents my current solution.
type calc struct {
fn func(a, b int) int
gn func(a string) bool
name string
}
func add(a, b int) int {
return a + b
}
func bar(foo string) bool {
// do something
}
func sub(a, b int) int {
return a - b
}
func main() {
for c := range []calc{{
fn: add,
gn: bar,
name: "addition",
}, {
fn: sub,
name: "subtraction",
}} {
fmt.Printf("%s(10, 15) returned: %d
", c.name, c.fn(10, 15))
if c.gn != nil {
c.gn(c.name)
}
}
}
My question is how to improve this code? What's the best way to achieve this in Go? Can I achieve a better solution using interface?
