Unless the change is a trivial fix such as for a typo, it's generally best to
start by opening a new issue describing the bug or feature you're intending to
fix. Even if you think it's relatively minor, it's helpful to know what people
are working on. And as mentioned above, API changes should be discussed
thoroughly before moving to code.

Und da die `Response` häufig zum Setzen von Headern und Cookies verwendet wird, stellt **FastAPI** diese auch unter `fastapi.Response` bereit.

When using **Pydantic v2**, the generated OpenAPI is a bit more exact and **correct** than before. 😎

In fact, in some cases, it will even have **two JSON Schemas** in OpenAPI for the same Pydantic model, for input and output, depending on if they have **default values**.

Let's see how that works and how to change it if you need to do that.

    void codes_are_non_negative_and_unique() {
        // Edge checks: ensure there are no negative or duplicate codes
        Set<Integer> seen = new HashSet<>();
        for (int c : WinError.WINERR_CODES) {
            assertTrue(c >= 0, "Code should be non-negative: " + c);
            assertTrue(seen.add(c), "Duplicate code detected: " + c);
        }
    }
