Defined in:
struct.c

#each {|obj| ... } ⇒ Object #each ⇒ Object

Calls block once for each instance variable, passing the value as a parameter.

If no block is given, an enumerator is returned instead.

Customer = Struct.new(:name, :address, :zip)
joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe.each {|x| puts(x) }

produces:

Joe Smith
123 Maple, Anytown NC
12345

Overloads:
