I need help with making this work for any type.
I have got a function I need to accept other types that have ID
property.
I have tried using interfaces but that did not work for my ID
property case. Here is the code:
package main
import (
"fmt"
"strconv"
)
type Mammal struct{
ID int
Name string
}
type Human struct {
ID int
Name string
HairColor string
}
func Count(ms []Mammal) *[]string { // How can i get this function to accept any type not just []Mammal
IDs := make([]string, len(ms))
for i, m := range ms {
IDs[i] = strconv.Itoa(int(m.ID))
}
return &IDs
}
func main(){
mammals := []Mammal{
Mammal{1, "Carnivorious"},
Mammal{2, "Ominivorious"},
}
humans := []Human{
Human{ID:1, Name: "Peter", HairColor: "Black"},
Human{ID:2, Name: "Paul", HairColor: "Red"},
}
numberOfMammalIDs := Count(mammals)
numberOfHumanIDs := Count(humans)
fmt.Println(numberOfMammalIDs)
fmt.Println(numberOfHumanIDs)
}
I get this
error prog.go:39: cannot use humans (type []Human) as type []Mammal in argument to Count
