An async mini ORM for Python, with support for Postgres, MySQL, and SQLite.

The main benefits of using ormar are:

* getting an async ORM that can be used with async frameworks (fastapi, starlette etc.) * getting just one model to maintain - you don't have to maintain pydantic and other orm models (sqlalchemy, peewee, gino etc.)

The goal was to create a simple ORM that can be used directly (as request and response models) with fastapi that bases it's data validation on pydantic.
