You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: types_exported_test.go
    path of file: ./repos/aws-sdk-go-v2/service/connectcases/types
    
    the code of the file until where you have to start completion: // Code generated by smithy-go-codegen DO NOT EDIT.

package types_test

import (
	"fmt"
	"github.com/aws/aws-sdk-go-v2/service/connectcases/types"
)

func ExampleAuditEventFieldValueUnion_outputUsage() {
	var union types.AuditEventFieldValueUnion
	// type switches can be used to check 
    
func ExampleFieldValueUnion_outputUsage() {
	var union types.FieldValueUnion
	// type switches can be used to check the union value
	switch v := union.(type) {
	case *types.FieldValueUnionMemberBooleanValue:
		_ = v.Value // Value is bool

	case *types.FieldValueUnionMemberDoubleValue:
		_ = v.Value // Value is float64

	case *types.FieldValueUnionMemberEmptyValue:
		_ = v.Value // Value is types.EmptyFieldValue

	case *types.FieldValueUnionMemberStringValue:
		_ = v.Value // Value is string

	case *types.FieldValueUnionMemberUserArnValue:
		_ = v.Value // Value is string

	case *types.UnknownUnionMember:
		fmt.Println("unknown tag:", v.Tag)

	default:
		fmt.Println("union is nil or unknown type")

	}
