Como o Pydantic fará a serialização no lado em **Rust**, você terá uma **performance** muito maior do que se não declarar um tipo de retorno.

### Funções de operação de rota não assíncronas { #non-async-path-operation-functions }

Você também pode usar funções `def` normais (sem `async`) e usar `yield` da mesma forma.

O FastAPI garantirá que sejam executadas corretamente para não bloquear o event loop.

    /**

     *
     * @param crudMode the CRUD mode for the operation
     * @param id the ID of the scheduled job to display
     * @return HTML response for the job details page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })

   * value} before proceeding with the {@link #put} operation. If the bimap previously contained the

        String[] msgs = DosError.DOS_ERROR_MESSAGES;

        // Assert
        assertNotNull(msgs);
        assertTrue(msgs.length >= 3, "Expect at least the first 3 entries present");
        assertEquals("The operation completed successfully.", msgs[0]);
        assertEquals("Incorrect function.", msgs[1]);
        assertEquals("Incorrect function.", msgs[2]);
    }

    @Test

    @Test
    @DisplayName("Should create SmbException with cause")
    void testSmbExceptionWithCause() {
        // Given
        Exception cause = new RuntimeException("Root cause");
        String message = "SMB operation failed";

        // When
        SmbException exception = new SmbException(message, cause);

        // Then
        assertNotNull(exception);
        assertEquals(message, exception.getMessage());

/// tip | Порада

Оскільки Pydantic серіалізує це на боці **Rust**, ви отримаєте значно вищу **продуктивність**, ніж якби не оголошували тип повернення.

### Не-async *функції операцій шляху* { #non-async-path-operation-functions }

Ви також можете використовувати звичайні функції `def` (без `async`) і використовувати `yield` так само.

FastAPI подбає про коректне виконання, щоб воно не блокувало цикл подій.
