Is there anyway that you can use the same function across multiple structs to satisfy an interface?
For example:
package main
import "fmt"
type Animal interface {
Speak() string
}
type Dog struct {}
func (d Dog) Speak() string {
return "Woof!"
}
type Wolf struct {}
func (w Wolf) Speak() string {
return "HOWWWWWWWWL"
}
type Beagle struct {}
func (b Beagle) Speak() string {
return "HOWWWWWWWWL"
}
type Cat struct {}
func (c Cat) Speak() string {
return "Meow"
}
func main() {
var a Animal
a = Wolf{}
fmt.Println(a.Speak())
}
Because Wolf and Beagle share the exact same function, is there anyway to write that function once, then share it between the two structs so that they both satisfy Animal?
