/// tip

Having the return model ensure that a value is always available and always `int` (not `None`) is very useful for the API clients, they can write much simpler code having this certainty.

Also, **automatically generated clients** will have simpler interfaces, so that the developers communicating with your API can have a much better time working with your API. 😎

At the very least in the short term the resource needs to know how to look up the component that is required to perform the work. This needs to be made simple, for the time being we can write and test plugins working in the same realm until we get complete isolation working.

h3. Plugins need a specific metadata model

func Test_newMetacacheStream(t *testing.T) {
	r := loadMetacacheSample(t)
	var buf bytes.Buffer
	w := newMetacacheWriter(&buf, 1<<20)
	defer w.Close()
	err := r.readFn(func(object metaCacheEntry) bool {
		err := w.write(object)
		if err != nil {
			t.Fatal(err)
		}
		return true
	})
	r.Close()
	if err != io.EOF {
		t.Fatal(err)
	}
	err = w.Close()
	if err != nil {
		t.Fatal(err)
	}

	hdr := &FileHeader{Name: "."}
	hdr.SetMode(fs.ModeDir | 0o755)
	w, err := zw.CreateHeader(hdr)
	if err != nil {
		t.Fatalf("create zip header: %v", err)
	}
	_, err = w.Write([]byte("some data"))
	if err != nil {
		t.Fatalf("write zip contents: %v", err)

	}
	err = zw.Close()
	if err != nil {
		t.Fatalf("close zip writer: %v", err)

	}

* If the PR is for a feature, it should have docs.
    * Unless it's a feature we want to discourage, like support for a corner case that we don't want users to use.
* The docs should include a source example file, not write Python directly in Markdown.
* If the source example(s) file can have different syntax for different Python versions, there should be different versions of the file, and they should be shown in tabs in the docs.

For example, to declare a query parameter `q` that can appear multiple times in the URL, you can write:

{* ../../docs_src/query_params_str_validations/tutorial011_an_py310.py hl[9] *}

Then, with a URL like:

```
http://localhost:8000/items/?q=foo&q=bar
```
