Documenting Contracts in OpenAPI

Fastapi-icontract provides the function fastapi_icontract.wrap_openapi_with_contracts() so that you can include the contracts in the openapi.json endpoint of your FastAPI app.

The function is called once the app has been fully specified (see the full example):

fastapi_icontract.wrap_openapi_with_contracts(app=app)

The function will override the app.openapi method and cache the results for efficiency.

The modified schema is afterwards available at app.openapi_url (usually set to the default "/openapi.json").
