struct methods.rb

$ Employee = Struct.new(:first_name, :last_name, :email, keyword_init: true)
=> Employee(keyword_init: true)

$ employee = Employee.new(first_name: "Eryan", last_name: "Cobham", email: "eryan@devmynd.com")
=> #<struct Employee first_name="Eryan", last_name="Cobham", email="eryan@devmynd.com">

# output all properties of the struct, even uninitialized ones
$ employee.members
=> [:first_name, :last_name, :email]

# output all of the set values
$ employee.values
=> ["Eryan", "Cobham", "eryan@devmynd.com"]

$ employee.select{ |value| value.start_with? "e" }
=> ["eryan@devmynd.com"]

$ employee.each{ |value| puts value }
