In the attached screenshot (taken from an exercise in “Programming Elixir”) can be shown that BugReport is defined as a struct that, itself, has as a value for one of its keys a struct: Customer.
Yet, when I tried, in iex, both the put_in function and its expanded form, when the owner key received a single string, succeeded.
My understanding of structs is that once I defined BugReport to take a Customer as the type of the key owner, it set in stone.
So, what am I misunderstanding about defining structs?
Thanks.
