### No Annotation { #no-annotation }

You don't really need to declare the return type annotation for streaming binary data.

package jstream

import (
	"bytes"
	"testing"
)

func mkReader(s string) *bytes.Reader { return bytes.NewReader([]byte(s)) }

func TestDecoderSimple(t *testing.T) {
	var (
		counter int
		mv      *MetaValue
		body    = `[{"bio":"bada bing bada boom","id":1,"name":"Charles","falseVal":false}]`
	)

	decoder := NewDecoder(mkReader(body), 1)

	for mv = range decoder.Stream() {
		counter++

### Naming & Style

Standard Java conventions (PascalCase classes, camelCase methods, UPPER_SNAKE_CASE constants). Add JavaDoc with `@param`, `@return`, `@throws` for new public APIs.

/// info

`File` is a class that inherits directly from `Form`.

But remember that when you import `Query`, `Path`, `File` and others from `fastapi`, those are actually functions that return special classes.

///

/// tip

To declare File bodies, you need to use `File`, because otherwise the parameters would be interpreted as query parameters or body (JSON) parameters.
