Struct MQPullConsumerScheduleService 

Source 
pub struct MQPullConsumerScheduleService { /* private fields */ }
👎Deprecated since 0.9.0:

Classic Pull scheduling is retained for compatibility; prefer application-owned scheduling for new code

Implementations§

Source§

impl MQPullConsumerScheduleService

Source

pub fn new(consumer_group: impl Into<CheetahString>) -> Self

Creates a detached compatibility value.

Use Self::with_client_runtime for a runnable schedule service.

Source

pub fn with_client_runtime( client_runtime: Arc<ClientRuntime>, consumer_group: impl Into<CheetahString>, ) -> ClientResult<Self>

Creates a schedule service backed by an application-owned client runtime.

§Errors

Returns an error when the consumer group or underlying Classic Pull configuration is invalid.

Source

pub fn consumer_group(&self) -> &CheetahString

Returns the configured consumer group.

Source

pub async fn start(&self) -> ClientResult<()>

Starts the consumer and its runtime-owned schedule coordinator.

§Errors

Returns an initialization error for a detached value, a stable lifecycle error for a repeated or invalid start, or an underlying consumer or task-spawn error.

Source

pub async fn shutdown(&self) -> ClientResult<()>

Cancels the coordinator, awaits it, and shuts down the consumer.

§Errors

Returns an initialization error for a detached value, an underlying consumer shutdown error, or a timeout when the coordinator does not stop within the shutdown bound.

Source

pub fn set_refresh_interval( &self, refresh_interval: Duration, ) -> ClientResult<()>

Sets how frequently the coordinator refreshes registered topic routes.

§Errors

Returns an error for a zero duration or a detached schedule service.

Source

pub fn register_pull_task_callback<C>( &self, topic: impl Into<CheetahString>, callback: C, ) -> ClientResult<()>
where C: PullTaskCallback,

Registers or replaces the callback for a topic.

§Errors

Returns an error for a blank topic or a detached schedule service.

Source

pub fn default_mq_pull_consumer(&self) -> ClientResult<DefaultMQPullConsumer>

Returns the schedule service’s Classic Pull consumer.

§Errors

Returns an initialization error for a detached schedule service.
