OpenStruct#to_h

ostruct.to_h → hash

ostruct.to_h {|name, value| block } → hash

# File tmp/rubies/ruby-3.0.5/lib/ostruct.rb, line 169
def to_h(&block)
  if block
    @table.to_h(&block)
  else
    @table.dup
  end
end

Converts the OpenStruct to a hash with keys representing each attribute (as symbols) and their corresponding values.

If a block is given, the results of the block on each pair of the receiver will be used as pairs.

Example

require "ostruct"
data = OpenStruct.new("country" => "Australia", :capital => "Canberra")
data.to_h   # => {:country => "Australia", :capital => "Canberra" }
data.to_h {|name, value| [name.to_s, value.upcase] }
            # => {"country" => "AUSTRALIA", "capital" => "CANBERRA" }
