## Starlette functies

**FastAPI** is volledig verenigbaar met (en gebaseerd op) <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a>.

`FastAPI` is eigenlijk een subklasse van `Starlette`. Dus als je Starlette al kent of gebruikt, zal de meeste functionaliteit op dezelfde manier werken.

Met **FastAPI** krijg je alle functies van **Starlette** (FastAPI is gewoon Starlette op steroïden):

* `gt`: `g`reater `t`han
* `ge`: `g`reater than or `e`qual
* `lt`: `l`ess `t`han
* `le`: `l`ess than or `e`qual

/// info

`Query`, `Path`, and other classes you will see later are subclasses of a common `Param` class.

All of them share the same parameters for additional validation and metadata you have seen.

            params_to_process[key] = value

        field_info = first_field.field_info
        assert isinstance(
            field_info, params.Param
        ), "Params must be subclasses of Param"
        loc: Tuple[str, ...] = (field_info.in_.value,)
        v_, errors_ = _validate_value_with_model_field(
            field=first_field, value=params_to_process, values=values, loc=loc
        )
