Rust Extension Methods

An example of using Extention Methods to pimp my library with a json generating method. The idea is that you have a clean create with the library code and a seperate create with the extention methods. This avoids having 3rd party marcos like serde as a dependency on your clean library code.

This project is a workspace containing two libraries and a binary project.

The libraries are:

• some_library which contains an enum Shape. This library has no external dependencies.
• some_extention contains a trait JSON which adds an Extention Method to_json onto Shape by wrapping it in Shaper to get around the Orphan rules. The Shaper class uses the serde remote derive technique Deriving De/Serialize for type in a different crate
