## Use the instance as a dependency

Then, we could use this `checker` in a `Depends(checker)`, instead of `Depends(FixedContentQueryChecker)`, because the dependency is the instance, `checker`, not the class itself.

And when solving the dependency, **FastAPI** will call this `checker` like:

```Python
checker(q="somequery")
```

  `comp:` etc.  At this stage we check if the PR is valid and meets certain
  quality requirements. For example, we check if the CLA is signed, PR has
  sufficient description, if applicable unit tests are added, if it is a
  reasonable contribution (meaning it is not a single liner cosmetic PR).

**2. Valid?**

-   If the PR passes all the quality checks then we go ahead and assign a
    reviewer.

 - [ ] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
 - [ ] Run `mvn clean verify` to make sure basic checks pass. A more thorough check will
       be performed on your pull request automatically.
 - [ ] You have run the [Core IT][core-its] successfully.

If your pull request is about ~20 lines of code you don't need to sign an

  duration: Long,
  unit: TimeUnit,
): Int {
  check(duration >= 0L) { "$name < 0" }
  val millis = unit.toMillis(duration)
  require(millis <= Integer.MAX_VALUE) { "$name too large" }
  require(millis != 0L || duration <= 0L) { "$name too small" }
  return millis.toInt()
}

internal fun checkDuration(
  name: String,
  duration: Duration,
): Int {
  check(!duration.isNegative()) { "$name < 0" }

        add(ia.next())

      if (ib.hasNext()) {
        add(ib.next())
      }
    }
  }

    assertThat(verifier.verify("℡.com", session)).isFalse()

    // These should ideally be false, but we know that hostname is usually already checked by us
    assertThat(verifier.verify("\u212A.com", session)).isFalse()

## Die Instanz als Abhängigkeit verwenden

Dann könnten wir diesen `checker` in einem `Depends(checker)` anstelle von `Depends(FixedContentQueryChecker)` verwenden, da die Abhängigkeit die Instanz `checker` und nicht die Klasse selbst ist.

Und beim Auflösen der Abhängigkeit ruft **FastAPI** diesen `checker` wie folgt auf:

```Python
checker(q="somequery")
