从结构切片动态创建map [string] struct的通用函数

Question

I have two different struct as mentioned below A abd B and two process functions. Is there any way by means of which i can write a common function to generate the map[string]struct for the both the struct. Moreover, is there any way using reflection given the struct name i can create the object of the same?

type A struct {
    name string
    // more fields
}


type B struct {
    name string
    // more fields  
}

func ProcessA(input []A) map[string]A {
    output := make(map[string]A)
    for _, v := range input {
         output[v.name] = v
    }
  return output
}


func ProcessB(input []B) map[string]B {
    output := make(map[string]B)
    for _, v := range input {
         output[v.name] = v
    }
  return output
}

Idiomatic way in Go would be to use interface.

type Named interface {
  Name() string
}

type letter struct {
  name string
}

func (l letter) Name() string {
  return l.name
}


type A struct {
    letter
    // more fields
}


type B struct {
    letter
    // more fields  
}

func ProcessNameds(input []Named) map[string]Named {
    output := make(map[string]Named, len(input))
    for _, v := range input {
         output[v.Name()] = v
    }
  return output
}
