/// note

Você só pode usar `await` dentro de funções criadas com `async def`.

///

---

Se você está usando biblioteca de terceiros que se comunica com alguma coisa (um banco de dados, uma API, sistema de arquivos etc) e não tem suporte para utilizar `await` (esse é atualmente o caso para a maioria das bibliotecas de banco de dados), então declare suas *funções de operação de rota* normalmente, com apenas `def`, como:

import assertk.assertions.isTrue
import java.util.concurrent.TimeUnit
import kotlin.test.assertFailsWith
import okhttp3.CacheControl.Companion.parse
import okhttp3.Headers.Companion.headersOf
import org.junit.jupiter.api.Test

class CacheControlJvmTest {
  @Test
  @Throws(Exception::class)
  fun completeBuilder() {
    val cacheControl =
      CacheControl
        .Builder()
        .noCache()
        .noStore()

   - Use `[WIP]` for in-progress PRs to avoid premature merging or choose GitHub draft PRs.

2. **Commits**:
   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
