Overview

FlexStruct provides a struct by which accessing undefined fields returns nil

struct = FlexStruct.new({ “foo” => 1, “bar” => [{ “baz” => 2 }, 3] })

struct.foo? # => true struct.brr? # => false struct.foo # => 1 struct.bar # => [FlexStruct<{ “baz” => 2 }>, 3] struct.brr # => nil struct # => 1 struct # => nil struct[:bar, 0, :baz] # => 2 struct[:bar, 0, :brr] # => nil
