Types

type Publisher

type Publisher struct {
	// contains filtered or unexported fields
}

Publisher is a wrapper with added distributed tracing capabilities.

Example

// Create the SQS API with the required config, credentials, etc.
sess, err := session.NewSession(
	aws.NewConfig().
		WithEndpoint("http://localhost:4576").
		WithRegion("eu-west-1").
		WithCredentials(
			credentials.NewStaticCredentials("aws-id", "aws-secret", "aws-token"),
		),
)
if err != nil {
	log.Fatal(err)
}

api := sqs.New(sess)

pub, err := New(api)
if err != nil {
	log.Fatal(err)
}

msg := &sqs.SendMessageInput{
	MessageBody: aws.String("message body"),
	QueueUrl:    aws.String("http://localhost:4576/queue/foo-queue"),
}

msgID, err := pub.Publish(context.Background(), msg)
if err != nil {
	log.Fatal(err)
}

fmt.Println(msgID)

func New

func New(api sqsiface.SQSAPI) (Publisher, error)

New creates a new SQS publisher.

func (Publisher) Publish

func (p Publisher) Publish(ctx context.Context, msg *sqs.SendMessageInput) (messageID string, err error)

Publish tries to publish a new message to SQS. It also stores tracing information.
