	// So if the result length is larger than an empirically-found
	// limit (8KB), we stop growing the source string once the limit
	// is reached and keep reusing the same source string - that
	// should therefore be always resident in the L1 cache - until we
	// have completed the construction of the result.
	// This yields significant speedups (up to +100%) in cases where
	// the result length is large (roughly, over L2 cache size).

Os parâmetros `prefix`, `tags`, `responses` e `dependencies` são (como em muitos outros casos) apenas um recurso do **FastAPI** para ajudar a evitar duplicação de código.

### Importar as dependências

Este código reside no módulo `app.routers.items`, o arquivo `app/routers/items.py`.

E precisamos obter a função de dependência do módulo `app.dependencies`, o arquivo `app/dependencies.py`.

	getNewIdent := ast.NewIdent
	if addPosition {
		getNewIdent = func(newName string) *ast.Ident {
			mangledIdent := ast.NewIdent(newName)
			if len(newName) == len(r.Name.Go) {
				return mangledIdent
			}
			p := fset.Position((*r.Expr).End())
			if p.Column == 0 {
				return mangledIdent
			}
			return ast.NewIdent(fmt.Sprintf("%s /*line :%d:%d*/", newName, p.Line, p.Column))

apps may target different 'environments' which contain different instances and variants of Istio.

- Better security: separate Istio components reside in different namespaces, allowing different teams or
roles to manage different parts of Istio. For example, a security team would maintain the
root CA and policy, a telemetry team may only have access to Prometheus,

The benefit of raising an exception over `return`ing a value will be more evident in the section about Dependencies and Security.

In this example, when the client requests an item by an ID that doesn't exist, raise an exception with a status code of `404`:
