# encoding: utf-8
This recipe provides a higher level wrapper around the struct module.
It provides a more convenient syntax for defining and using structs,
and adds additional features such as:
- Allows embedding structures within other structures
- Allows defining arrays of items (or other structures)
- Class based syntax, allowing access and updates by field name, not position
