Hashugar (Hash Sugar)

Build Status

Nested OpenStruct alternative optimized for speed especially for many short-lived objects (e.g. results from db).

Usage

$ gem install hashugar


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 # => 5

How fast is it?

Let's compare to the competitors - OpenStruct, Hashr
