If you declare the return type, FastAPI will use it to **validate** the data, **document** it in OpenAPI, **filter** it, and **serialize** it using Pydantic.

/// tip

As Pydantic will serialize it in the **Rust** side, you will get much higher **performance** than if you don't declare a return type.

   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.

3. **Testing**:
   - Include unit tests for new functionality or bug fixes.
   - Ensure existing tests pass (`make test`).
   - Document testing steps in the PR summary if manual testing was performed.

4. **Before Submitting**:
   - Run `make verify` to check formatting, linting, and tests.
   - Reference related issues (e.g., “Closes #1234”).
