Cosmos::MultiFieldBitConversion

A cosmos read conversion designed to combine the bits of several uint fields. Where values on the left are more significant, and values on the right are less significant. This conversaion will work with any number of uint fields, of any size.

Add this line to your application's Gemfile:

gem 'cosmos-multi_field_bit_conversion'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cosmos-multi_field_bit_conversion
