Struct StartExecutionFluentBuilder

pub struct StartExecutionFluentBuilder { /* private fields */ }

Fluent builder constructing a request to StartExecution.

Starts a state machine execution.

A qualified state machine ARN can either refer to a Distributed Map state defined within a state machine, a version ARN, or an alias ARN.

The following are some examples of qualified and unqualified state machine ARNs:

• The following qualified state machine ARN refers to a Distributed Map state with a label mapStateLabel in a state machine named myStateMachine.

  arn:partition:states:region:account-id:stateMachine:myStateMachine/mapStateLabel

  If you provide a qualified state machine ARN that refers to a Distributed Map state, the request fails with ValidationException.

• The following qualified state machine ARN refers to an alias named PROD.

  arn: :states: : :stateMachine:

  If you provide a qualified state machine ARN that refers to a version ARN or an alias ARN, the request starts execution for that version or alias.

• The following unqualified state machine ARN refers to a state machine named myStateMachine.

  arn: :states: : :stateMachine:

If you start an execution with an unqualified state machine ARN, Step Functions uses the latest revision of the state machine for the execution.

To start executions of a state machine version, call StartExecution and provide the version ARN or the ARN of an alias that points to the version.

StartExecution is idempotent for STANDARD workflows. For a STANDARD workflow, if you call StartExecution with the same name and input as a running execution, the call succeeds and return the same response as the original request. If the execution is closed or if the input is different, it returns a 400 ExecutionAlreadyExists error. You can reuse names after 90 days.

StartExecution isn't idempotent for EXPRESS workflows.

Implementations

impl StartExecutionFluentBuilder

pub fn as_input(&self) -> &StartExecutionInputBuilder

Access the StartExecution as a reference.

pub async fn send( self, ) -> Result<StartExecutionOutput, SdkError<StartExecutionError, HttpResponse>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn customize( self, ) -> CustomizableOperation<StartExecutionOutput, StartExecutionError, Self>

Consumes this builder, creating a customizable operation that can be modified before being sent.

pub fn state_machine_arn(self, input: impl Into<String>) -> Self

The Amazon Resource Name (ARN) of the state machine to execute.

The stateMachineArn parameter accepts one of the following inputs:

• An unqualified state machine ARN – Refers to a state machine ARN that isn't qualified with a version or alias ARN. The following is an example of an unqualified state machine ARN.

  arn: :states: : :stateMachine:

  Step Functions doesn't associate state machine executions that you start with an unqualified ARN with a version. This is true even if that version uses the same revision that the execution used.

• A state machine version ARN – Refers to a version ARN, which is a combination of state machine ARN and the version number separated by a colon (:). The following is an example of the ARN for version 10.

  arn: :states: : :stateMachine: :10

  Step Functions doesn't associate executions that you start with a version ARN with any aliases that point to that version.

• A state machine alias ARN – Refers to an alias ARN, which is a combination of state machine ARN and the alias name separated by a colon (:). The following is an example of the ARN for an alias named PROD.

  arn: :states: : :stateMachine:

  Step Functions associates executions that you start with an alias ARN with that alias and the state machine version used for that execution.

pub fn set_state_machine_arn(self, input: Option<String>) -> Self

The Amazon Resource Name (ARN) of the state machine to execute.

The stateMachineArn parameter accepts one of the following inputs:

  arn: :states: : :stateMachine:

  Step Functions associates executions that you start with an alias ARN with that alias and the state machine version used for that execution.

pub fn get_state_machine_arn(&self) -> &Option<String>

The Amazon Resource Name (ARN) of the state machine to execute.

The stateMachineArn parameter accepts one of the following inputs:

  arn: :states: : :stateMachine:

  Step Functions associates executions that you start with an alias ARN with that alias and the state machine version used for that execution.

pub fn name(self, input: impl Into<String>) -> Self

Optional name of the execution. This name must be unique for your Amazon Web Services account, Region, and state machine for 90 days. For more information, see Limits Related to State Machine Executions in the Step Functions Developer Guide.

If you don't provide a name for the execution, Step Functions automatically generates a universally unique identifier (UUID) as the execution name.

A name must not contain:

• white space

• brackets < > { } \[ \]

• wildcard characters ? *

• special characters " # % \ ^ | ~ ` $ & , ; : /

• control characters (U+0000-001F, U+007F-009F, U+FFFE-FFFF)

• surrogates (U+D800-DFFF)

• invalid characters ( U+10FFFF)

To enable logging with CloudWatch Logs, the name should only contain 0-9, A-Z, a-z, - and _.

pub fn set_name(self, input: Option<String>) -> Self

Optional name of the execution. This name must be unique for your Amazon Web Services account, Region, and state machine for 90 days. For more information, see Limits Related to State Machine Executions in the Step Functions Developer Guide.

If you don't provide a name for the execution, Step Functions automatically generates a universally unique identifier (UUID) as the execution name.

A name must not contain:

• white space

• brackets < > { } \[ \]

• wildcard characters ? *

• special characters " # % \ ^ | ~ ` $ & , ; : /

• control characters (U+0000-001F, U+007F-009F, U+FFFE-FFFF)

• surrogates (U+D800-DFFF)

• invalid characters ( U+10FFFF)

pub fn input(self, input: impl Into<String>) -> Self

The string that contains the JSON input data for the execution, for example:

"{\"first_name\" : \"Alejandro\"}"

If you don't include any JSON input data, you still must include the two braces, for example: "{}"

Length constraints apply to the payload size, and are expressed as bytes in UTF-8 encoding.

pub fn set_input(self, input: Option<String>) -> Self

The string that contains the JSON input data for the execution, for example:

"{\"first_name\" : \"Alejandro\"}"

If you don't include any JSON input data, you still must include the two braces, for example: "{}"

pub fn trace_header(self, input: impl Into<String>) -> Self

Passes the X-Ray trace header. The trace header can also be passed in the request payload.

For X-Ray traces, all Amazon Web Services services use the X-Amzn-Trace-Id header from the HTTP request. Using the header is the preferred mechanism to identify a trace. StartExecution and StartSyncExecution API operations can also use traceHeader from the body of the request payload. If both sources are provided, Step Functions will use the header value (preferred) over the value in the request body.

pub fn set_trace_header(self, input: Option<String>) -> Self

Passes the X-Ray trace header. The trace header can also be passed in the request payload.
