How to validate slice of struct ?

[mdsohelmia]

  type User struct {
	  FirstName string
	  LastName string
	  Address AddressSliceWrapper
  }
  
  type Address struct {
	  IsMailing bool 
  }
  
  type Addresses []Address

// AddressSliceWrapper embeds the alias type for the sake of embedding a slice.
// This is very heavy-handed.

type AddressSliceWrapper struct {
	Addresses
}
