Ruby Structs Example
Structs are a built-in Ruby class that can act like a custom class. They are great for testing, debugging and playing.
LunchOrder = Struct.new(:name, :drink, :food)
event_order = []
event_order << LunchOrder.new('hakeem', 'water', 'Mixed Veggie')
event_order << LunchOrder.new('selena', 'mango lasse', 'Bangkok Dumplings')
event_order << LunchOrder.new('jingyan', 'tea', 'Yellow Curry')
drinks = event_order.map(&:drink)
Structs are compared by value equality rather than referential equality. If two struct objects have the same value they are equal. Classes with the same values are not equal.
