How to create a new data type which to can check/validate its schema when is created a new variable (of that type)?

By example, to validate if a string has 20 characters, I tried:

{{{ // Format: 2006-01-12T06:06:06Z func date(str string) { if len(str) != 20 { fmt.Println("error") } } var Date = date()

type Account struct { domain string username string created Date } }}}

but it faills because Date is not a type.
