Nested OpenStruct alternative optimized for speed especially for many short-lived objects (e.g. results from db).
TODO: deploy this gem under a CI system
$ gem install hashugar
Basic examples:
hashugar = {:a => 1, 'b' => {:c => 2, :d => [3, 4, {:e => 5}]}}.to_hashugar
hashugar.a # => 1
hashugar.b.c # => 2
hashugar.b.d.last.e # => 5Convert a Hashugar object back to a regular Ruby Hash recursively:
hashugar.to_new_hash # => {:a => 1, 'b' => {:c => 2, :d => [3, 4, {:e => 5}]}}
Teach Hashugar methods from other compatible classes (currently only Hash supported):
hashugar = { one: 1, two: 2 }.to_hashugar
hashugar.clear # => nil
Hashugar.learn_methods Hash
hashugar.clear # => {}Let's compare to the competitors - OpenStruct, Hashr
