## Automatic conversion { #automatic-conversion }

`Header` has a little extra functionality on top of what `Path`, `Query` and `Cookie` provide.

Most of the standard headers are separated by a "hyphen" character, also known as the "minus symbol" (`-`).

But a variable like `user-agent` is invalid in Python.

For now, you just need to know that `Annotated` exists, and that it's standard Python. 😎

Later you will see how **powerful** it can be.

/// tip

The fact that this is **standard Python** means that you will still get the **best possible developer experience** in your editor, with the tools you use to analyze and refactor your code, etc. ✨

                    return new StandardImplForwardingSet<>(new LinkedHashSet<>(asList(elements)));
                  }
                })
            .named("ForwardingSet[LinkedHashSet] with standard implementations")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.ALLOWS_NULL_VALUES,
                CollectionFeature.GENERAL_PURPOSE)
            .createTestSuite());

```JSON
{"item_id":"foo"}
```

## Path parameters with types { #path-parameters-with-types }

You can declare the type of a path parameter in the function, using standard Python type annotations:

{* ../../docs_src/path_params/tutorial002_py39.py hl[7] *}

In this case, `item_id` is declared to be an `int`.

/// check

	ARN          string
	// EncryptionConfiguration TODO: not needed for MinIO
}

func (d Destination) isValidStorageClass() bool {
	if d.StorageClass == "" {
		return true
	}
	return d.StorageClass == "STANDARD" || d.StorageClass == "REDUCED_REDUNDANCY"
}

// IsValid - checks whether Destination is valid or not.
func (d Destination) IsValid() bool {
	return d.Bucket != "" || !d.isValidStorageClass()
}

                    return new StandardImplForwardingSet<>(new LinkedHashSet<>(asList(elements)));
                  }
                })
            .named("ForwardingSet[LinkedHashSet] with standard implementations")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.ALLOWS_NULL_VALUES,
                CollectionFeature.GENERAL_PURPOSE)
            .createTestSuite());

Two file sizes are used -- regular (1.6mb, 1000 objects) and large (128mb, 100000 objects)

input size | lib | MB/s | Allocated
--- | --- | --- | ---
regular | standard | 97 | 3.6MB
regular | jstream | 175 | 2.1MB
large | standard | 92 | 305MB
large | jstream | 404 | 69MB

In a real world scenario, including initialization and reader overhead from varying blob sizes, performance can be expected as below:

```JSON
{"item_id":"foo"}
```

## Pfad-Parameter mit Typen { #path-parameters-with-types }

Sie können den Typ eines Pfad-Parameters in der Argumentliste der Funktion deklarieren, mit Standard-Python-Typannotationen:

{* ../../docs_src/path_params/tutorial002_py39.py hl[7] *}

In diesem Fall wird `item_id` als `int` deklariert, also als Ganzzahl.
