***DOCUMENTATION ON DOCS.RS***  

***PURPOSE***  
The parser uses the Pest library to define grammar rules that interpret specific `.yaml` structures. It parses:
- Schema name
- Tables within the schema
- Columns their types and modes within each table

The parsed data can be used to generate structured representation of database schemas for your application.
