Struct DecisionTask

pub struct DecisionTask {
    pub events: Vec<HistoryEvent>,
    pub next_page_token: Option<String>,
    pub previous_started_event_id: Option<i64>,
    pub started_event_id: i64,
    pub task_token: String,
    pub workflow_execution: WorkflowExecution,
    pub workflow_type: WorkflowType,
}

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

Fields

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: Option<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.

started_event_id: i64

The ID of the DecisionTaskStarted event recorded in the history.

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.

workflow_execution: WorkflowExecution

The workflow execution for which this decision task was created.

workflow_type: WorkflowType

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

Trait Implementations

impl Clone for DecisionTask

fn clone(&self) -> DecisionTask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecisionTask

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

Formats the value using the given formatter.

impl Default for DecisionTask

fn default() -> DecisionTask

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DecisionTask

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DecisionTask

fn eq(&self, other: &DecisionTask) -> 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.
