[🔗](https://github.com/xinz/oasis/blob/main/lib/oasis/plug/request_validator.ex#L1)

A plug to convert types and validate the HTTP request parameters by the schemas of
the OpenAPI definition.

The schema options can be found in the generated `pre-` plug handler file, the full list:

  * `:query_schema`
  * `:header_schema`
  * `:cookie_schema`
  * `:body_schema`

All of these options are fully map and generated from the corresponding definition of the OpenAPI Specification.

When the query parameters are verified by the validation of `:query_schema`, the coverted types of query parameters
are reserved in `:query_params` and `:params` field of the `Plug.Conn`.

When the header parameters are verified by the validation of `:header_schema`, the converted types of header parameters
are reserved in `:req_headers` field of the `Plug.Conn`.

When the cookie parameters are verified by the validation of `:cookie_schema`, the coverted types of cookie parameters
are reserved in `:req_cookies` field of the `Plug.Conn`.

When the request body is verified by the validation of `:body_schema`, the coverted types of request body are reserved
in `:body_params` and `:params` field of the `Plug.Conn`.
