This small gem will help you achieve exactly that without any re-design of the objects you already have. Just decorate them with `SyncEm` [thread-safe decorator](https://www.yegor256.com/2017/01/17/synchronized-decorators.html) and that is it. First, install it: ```bash $ gem install syncem ``` Then, use it like this: ```ruby require 'syncem' obj = SyncEm.new(obj) ``` That's it. ## How to contribute Read [these guidelines](https://www.yegor256.com/2014/04/15/github-guidelines.html).
