Should nested structs support metadata?

1

Is this possible some other way?

require 'dry-types'
require 'dry-struct'

module Types
  include Dry::Types.module
end

class Address < Dry::Struct
  attribute :street, Types::Strict::String.meta(key: 'fk_street')
end

class Customer < Dry::Struct
  attribute :address, Address.meta(key: 'fk_address')
end

customer = Customer.new(address: { street: 'foo' })
