Types ¶
type Listener ¶
type Listener struct {
// contains filtered or unexported fields
}
Listener is a struct to contain service bus entities relevant to subscribing to a publisher topic
func New ¶
func New(opts ...ManagementOption) (*Listener, error)
New creates a new service bus listener
func (*Listener) GetActiveMessageCount ¶ added in v0.5.3
func (l *Listener) GetActiveMessageCount(ctx context.Context, topicName, subscriptionName string) (int32, error)
GetActiveMessageCount gets the active message count of a topic subscription WARNING: GetActiveMessageCount is 10 times expensive than a call to receive a message
func (*Listener) Listen ¶
func (l *Listener) Listen(ctx context.Context, handler message.Handler, topicName string, opts ...Option) error
Listen waits for a message from the Service Bus Topic subscription
func (*Listener) Namespace ¶
func (l *Listener) Namespace() *servicebus.Namespace
Namespace returns the servicebus.Namespace that the listener is setup with
func (*Listener) Subscription ¶
func (l *Listener) Subscription() *servicebus.SubscriptionEntity
Subscription returns the servicebus.SubscriptionEntity that the listener is setup with
func (*Listener) Topic ¶
func (l *Listener) Topic() *servicebus.TopicEntity
Topic returns servicebus.TopicEntity that the listener is setup with
type ManagementOption ¶
ManagementOption provides structure for configuring a new Listener
func WithConnectionString ¶
func WithConnectionString(connStr string) ManagementOption
WithConnectionString configures a listener with the information provided in a Service Bus connection string
func WithFilterDescriber ¶
func WithFilterDescriber(filterName string, filter servicebus.FilterDescriber) ManagementOption
WithFilterDescriber configures the filters on the subscription
func WithManagedIdentityClientID ¶
func WithManagedIdentityClientID(serviceBusNamespaceName, managedIdentityClientID string) ManagementOption
WithManagedIdentityClientID configures a listener with the attached managed identity and the Service bus resource name
func WithManagedIdentityResourceID ¶
func WithManagedIdentityResourceID(serviceBusNamespaceName, managedIdentityResourceID string) ManagementOption
WithManagedIdentityResourceID configures a listener with the attached managed identity and the Service bus resource name
func WithSubscriptionDetails ¶ added in v0.6.0
func WithSubscriptionDetails(lock time.Duration, maxDelivery int32) ManagementOption
WithSubscriptionDetails allows listeners to control subscription details for longer lived operations. If you using RetryLater you probably want this. Passing zeros leaves it up to Service bus defaults
func WithSubscriptionName ¶
func WithSubscriptionName(name string) ManagementOption
WithSubscriptionName configures the subscription name of the subscription to listen to
func WithToken ¶
func WithToken(serviceBusNamespaceName string, spt *adal.ServicePrincipalToken) ManagementOption
WithToken configures a listener with a AAD token
type Option ¶
Option provides structure for configuring when starting to listen to a specified topic
func WithMaxConcurrency ¶ added in v0.6.1
func WithMessageLockAutoRenewal ¶ added in v0.6.1
func WithPrefetchCount ¶ added in v0.6.1
WithPrefetchCount the receiver to quietly acquires more messages, up to the PrefetchCount limit. A single Receive call to the ServiceBus api therefore acquires several messages for immediate consumption that is returned as soon as available. Please be aware of the consequences : https://docs.microsoft.com/en-us/azure/service-bus-messaging/service-bus-prefetch#if-it-is-faster-why-is-prefetch-not-the-default-option
