Let's imagine that loading the model can **take quite some time**, because it has to read a lot of **data from disk**. So you don't want to do it for every request.

Reading a file from disk is normally a costly (slow) operation, so you probably want to do it only once and then re-use the same settings object, instead of reading it for each request.

But every time we do:

```Python
Settings()
```

a new `Settings` object would be created, and at creation it would read the `.env` file again.

If the dependency function was just like:

```Python

 * it requires that the complete universe of rows and columns be specified at construction time.
 * Second, it is always backed by an array large enough to hold a value for every possible
 * combination of row and column keys. (This is rarely optimal unless the table is extremely dense.)
 * Finally, every possible combination of row and column keys is always considered to have a value

    fun setUp() {
        val stepsCapturer = slot<BuildSteps.() -> Unit>()
        every { buildType.steps } returns steps
        every {
            buildType.steps(capture(stepsCapturer))
        } answers {
            stepsCapturer.captured(steps)
            mockk()
        }
    }

# Dependencies

**FastAPI** has a very powerful but intuitive **<abbr title="also known as components, resources, providers, services, injectables">Dependency Injection</abbr>** system.

It is designed to be very simple to use, and to make it very easy for any developer to integrate other components with **FastAPI**.

## What is "Dependency Injection"

	m := podsRepaired.With(typeLabel.Value(repairType))
	log := repairLog.WithLabels("pod", pod.Namespace+"/"+pod.Name)
	key := types.NamespacedName{Name: pod.Name, Namespace: pod.Namespace}
	// We will get an event every time the pod changes. The repair is not instantaneous, though -- it will only recover
	// once the pod restarts (in CrashLoopBackoff), which can take some time.

   *
   * <p>The returned set isn't threadsafe or serializable, even if {@code unfiltered} is.
   *
   * <p>Many of the filtered set's methods, such as {@code size()}, iterate across every element in
   * the underlying set and determine which elements satisfy the filter. When a live view is
   * <i>not</i> needed, it may be faster to copy {@code Iterables.filter(unfiltered, predicate)} and
   * use the copy.
