Subject: [ruby-core:41261] [ruby-trunk - Feature #4862] Struct#to_hash


Issue #4862 has been updated by Thomas Sawyer.


Then again maybe I'm wrong b/c I was just surprised by the fact that a Struct doesn't have (or at least act like it has) instance_variables.

  Struct.new(:a).new(1).instance_variables  #=> []

Occasionally, it is necessary to convert a Struct to a Hash (especially when generating JSON from an Array of Structs). A Struct#to_hash method would be very useful in this situation.

    class Struct

      #
      # Returns the Hash representation of the members and values within the struct.
      #
      def to_hash
        new_hash = {}

        each_pair do |member,value|
          new_hash[member] = value
        end

        new_hash
      end

    end
