I need to create a slice of struct from its interface with reflection.
I used Reflection because do not see any other solution without using it.
Briefly, the function receives variadic values of Interface.
Then, with reflection creates slice and passes it into another function.
Reflection asks to type assertion
SliceVal.Interface().(SomeStructType)
But, I cannot use it.
Code in playground http://ift.tt/187mdnN
The code:
package main
import (
"fmt"
"reflect"
)
type Model interface {
Hi()
}
type Order struct {
H string
}
func (o Order) Hi() {
fmt.Println("hello")
}
func Full(m []Order) []Order{
o := append(m, Order{H:"Bonjour"}
return o
}
func MakeSlices(models ...Model) {
for _, m := range models {
v := reflect.ValueOf(m)
fmt.Println(v.Type())
sliceType := reflect.SliceOf(v.Type())
emptySlice := reflect.MakeSlice(sliceType, 1, 1)
Full(emptySlice.Interface())
}
}
func main() {
MakeSlices(Order{})
}
