-Aiohttp pydantic is an `aiohttp view`_ to easily parse and validate request.
-You define using the function annotations what your methods for handling HTTP verbs expects and Aiohttp pydantic parses the HTTP request
-for you, validates the data, and injects that you want as parameters.
-
-
-Features:
-
- Query string, request body, URL path and HTTP headers validation.
- Open API Specification generation.
