Struct PollForDecisionTaskOutput

#[non_exhaustive]
pub struct PollForDecisionTaskOutput {
    pub task_token: String,
    pub started_event_id: i64,
    pub workflow_execution: Option<WorkflowExecution>,
    pub workflow_type: Option<WorkflowType>,
    pub events: Vec<HistoryEvent>,
    pub next_page_token: Option<String>,
    pub previous_started_event_id: i64,
    /* private fields */
}

A structure that represents a decision task. Decision tasks are sent to deciders in order for them to make decisions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

task_token: String

The opaque string used as a handle on the task. This token is used by workers to communicate progress and response information back to the system about the task.

started_event_id: i64

The ID of the DecisionTaskStarted event recorded in the history.

workflow_execution: Option<WorkflowExecution>

The workflow execution for which this decision task was created.

workflow_type: Option<WorkflowType>

The type of the workflow execution for which this decision task was created.

events: Vec<HistoryEvent>

A paginated list of history events of the workflow execution. The decider uses this during the processing of the decision task.

next_page_token: Option<String>

If a NextPageToken was returned by a previous call, there are more results available. To retrieve the next page of results, make the call again using the returned token in nextPageToken. Keep all other arguments unchanged.

The configured maximumPageSize determines how many results can be returned in a single call.

previous_started_event_id: i64

The ID of the DecisionTaskStarted event of the previous decision task of this workflow execution that was processed by the decider. This can be used to determine the events in the history new since the last decision task received by the decider.

Implementations

impl PollForDecisionTaskOutput

pub fn task_token(&self) -> &str

The opaque string used as a handle on the task. This token is used by workers to communicate progress and response information back to the system about the task.

pub fn started_event_id(&self) -> i64

The ID of the DecisionTaskStarted event recorded in the history.

pub fn workflow_execution(&self) -> Option<&WorkflowExecution>

The workflow execution for which this decision task was created.

pub fn workflow_type(&self) -> Option<&WorkflowType>

The type of the workflow execution for which this decision task was created.

pub fn events(&self) -> &[HistoryEvent]

A paginated list of history events of the workflow execution. The decider uses this during the processing of the decision task.

pub fn next_page_token(&self) -> Option<&str>

If a NextPageToken was returned by a previous call, there are more results available. To retrieve the next page of results, make the call again using the returned token in nextPageToken. Keep all other arguments unchanged.

The configured maximumPageSize determines how many results can be returned in a single call.

pub fn previous_started_event_id(&self) -> i64

The ID of the DecisionTaskStarted event of the previous decision task of this workflow execution that was processed by the decider. This can be used to determine the events in the history new since the last decision task received by the decider.

impl PollForDecisionTaskOutput

pub fn builder() -> PollForDecisionTaskOutputBuilder

Creates a new builder-style object to manufacture PollForDecisionTaskOutput.

Trait Implementations

impl Clone for PollForDecisionTaskOutput

fn clone(&self) -> PollForDecisionTaskOutput

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PollForDecisionTaskOutput

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PollForDecisionTaskOutput

fn eq(&self, other: &PollForDecisionTaskOutput) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl RequestId for PollForDecisionTaskOutput

fn request_id(&self) -> Option<&str>

Returns the request ID, or None if the service could not be reached.
