Provides the details of the ContinueAsNewWorkflowExecution decision.

Access Control

You can use IAM policies to control this decision's access to Amazon SWF resources as follows:

• Use a Resource element with the domain name to limit the action to only specified domains.

• Use an Action element to allow or deny permission to call this action.

• Constrain the following parameters by using a Condition element with the appropriate keys.

  • tag – A tag used to identify the workflow execution

  • taskList – String constraint. The key is swf:taskList.name.

  • workflowType.version – String constraint. The key is swf:workflowType.version.

If the caller doesn't have sufficient permissions to invoke the action, or the parameter values fall outside the specified constraints, the action fails. The associated event attribute's cause parameter is set to OPERATION_NOT_PERMITTED. For details and example IAM policies, see Using IAM to Manage Access to Amazon SWF Workflows in the Amazon SWF Developer Guide.

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.

input: Option<String>

The input provided to the new workflow execution.

execution_start_to_close_timeout: Option<String>

If set, specifies the total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the workflow type.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

An execution start-to-close timeout for this workflow execution must be specified either as a default for the workflow type or through this field. If neither this field is set nor a default execution start-to-close timeout was specified at registration time then a fault is returned.

task_list: Option<TaskList>

The task list to use for the decisions of the new (continued) workflow execution.

task_priority: Option<String>

The task priority that, if set, specifies the priority for the decision tasks for this workflow execution. This overrides the defaultTaskPriority specified when registering the workflow type. Valid values are integers that range from Java's Integer.MIN_VALUE (-2147483648) to Integer.MAX_VALUE (2147483647). Higher numbers indicate higher priority.

For more information about setting task priority, see Setting Task Priority in the Amazon SWF Developer Guide.

task_start_to_close_timeout: Option<String>

Specifies the maximum duration of decision tasks for the new workflow execution. This parameter overrides the defaultTaskStartToCloseTimout specified when registering the workflow type using RegisterWorkflowType.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

A task start-to-close timeout for the new workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task start-to-close timeout was specified at registration time then a fault is returned.

child_policy: Option<ChildPolicy>

If set, specifies the policy to use for the child workflow executions of the new execution if it is terminated by calling the TerminateWorkflowExecution action explicitly or due to an expired timeout. This policy overrides the default child policy specified when registering the workflow type using RegisterWorkflowType.

The supported child policies are:

• TERMINATE – The child executions are terminated.

• REQUEST_CANCEL – A request to cancel is attempted for each child execution by recording a WorkflowExecutionCancelRequested event in its history. It is up to the decider to take appropriate actions when it receives an execution history with this event.

• ABANDON – No action is taken. The child executions continue to run.

A child policy for this workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default child policy was specified at registration time then a fault is returned.

tag_list: Option<Vec<String>>

The list of tags to associate with the new workflow execution. A maximum of 5 tags can be specified. You can list workflow executions with a specific tag by calling ListOpenWorkflowExecutions or ListClosedWorkflowExecutions and specifying a TagFilter.

workflow_type_version: Option<String>

The version of the workflow to start.

lambda_role: Option<String>

The IAM role to attach to the new (continued) execution.

Implementations

impl ContinueAsNewWorkflowExecutionDecisionAttributes

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

The input provided to the new workflow execution.

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

If set, specifies the total duration for this workflow execution. This overrides the defaultExecutionStartToCloseTimeout specified when registering the workflow type.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

An execution start-to-close timeout for this workflow execution must be specified either as a default for the workflow type or through this field. If neither this field is set nor a default execution start-to-close timeout was specified at registration time then a fault is returned.

pub fn task_list(&self) -> Option<&TaskList>

The task list to use for the decisions of the new (continued) workflow execution.

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

The task priority that, if set, specifies the priority for the decision tasks for this workflow execution. This overrides the defaultTaskPriority specified when registering the workflow type. Valid values are integers that range from Java's Integer.MIN_VALUE (-2147483648) to Integer.MAX_VALUE (2147483647). Higher numbers indicate higher priority.

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

Specifies the maximum duration of decision tasks for the new workflow execution. This parameter overrides the defaultTaskStartToCloseTimout specified when registering the workflow type using RegisterWorkflowType.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

A task start-to-close timeout for the new workflow execution must be specified either as a default for the workflow type or through this parameter. If neither this parameter is set nor a default task start-to-close timeout was specified at registration time then a fault is returned.

pub fn child_policy(&self) -> Option<&ChildPolicy>

If set, specifies the policy to use for the child workflow executions of the new execution if it is terminated by calling the TerminateWorkflowExecution action explicitly or due to an expired timeout. This policy overrides the default child policy specified when registering the workflow type using RegisterWorkflowType.

The supported child policies are:

• TERMINATE – The child executions are terminated.

pub fn tag_list(&self) -> &[String]

The list of tags to associate with the new workflow execution. A maximum of 5 tags can be specified. You can list workflow executions with a specific tag by calling ListOpenWorkflowExecutions or ListClosedWorkflowExecutions and specifying a TagFilter.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .tag_list.is_none().

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

The version of the workflow to start.

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

The IAM role to attach to the new (continued) execution.
