Enum StartWorkflowExecutionError

#[non_exhaustive]
pub enum StartWorkflowExecutionError {
    DefaultUndefinedFault(DefaultUndefinedFault),
    LimitExceededFault(LimitExceededFault),
    OperationNotPermittedFault(OperationNotPermittedFault),
    TypeDeprecatedFault(TypeDeprecatedFault),
    UnknownResourceFault(UnknownResourceFault),
    WorkflowExecutionAlreadyStartedFault(WorkflowExecutionAlreadyStartedFault),
    Unhandled(Unhandled),
}

Error type for the StartWorkflowExecutionError operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

DefaultUndefinedFault(DefaultUndefinedFault)

The StartWorkflowExecution API action was called without the required parameters set.

Some workflow execution parameters, such as the decision taskList, must be set to start the execution. However, these parameters might have been set as defaults when the workflow type was registered. In this case, you can omit these parameters from the StartWorkflowExecution call and Amazon SWF uses the values defined in the workflow type.

If these parameters aren't set and no default parameters were defined in the workflow type, this error is displayed.

LimitExceededFault(LimitExceededFault)

Returned by any operation if a system imposed limitation has been reached. To address this fault you should either clean up unused resources or increase the limit by contacting AWS.

OperationNotPermittedFault(OperationNotPermittedFault)

Returned when the caller doesn't have sufficient permissions to invoke the action.

TypeDeprecatedFault(TypeDeprecatedFault)

Returned when the specified activity or workflow type was already deprecated.

UnknownResourceFault(UnknownResourceFault)

Returned when the named resource cannot be found with in the scope of this operation (region or domain). This could happen if the named resource was never created or is no longer available for this operation.

WorkflowExecutionAlreadyStartedFault(WorkflowExecutionAlreadyStartedFault)

Returned by StartWorkflowExecution when an open execution with the same workflowId is already running in the specified domain.

Unhandled(Unhandled)

👎Deprecated: Matching Unhandled directly is not forwards compatible. Instead, match using a variable wildcard pattern and check .code():    err if err.code() == Some("SpecificExceptionCode") => { /* handle the error */ } See ProvideErrorMetadata for what information is available for the error.

An unexpected error occurred (e.g., invalid JSON returned by the service or an unknown error code).

Implementations

impl StartWorkflowExecutionError

pub fn unhandled(err: impl Into<Box<dyn Error + Send + Sync + 'static>>) -> Self

Creates the StartWorkflowExecutionError::Unhandled variant from any error type.

pub fn generic(err: ErrorMetadata) -> Self

Creates the StartWorkflowExecutionError::Unhandled variant from an ErrorMetadata.

pub fn meta(&self) -> &ErrorMetadata

Returns error metadata, which includes the error code, message, request ID, and potentially additional information.

pub fn is_default_undefined_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::DefaultUndefinedFault.

pub fn is_limit_exceeded_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::LimitExceededFault.

pub fn is_operation_not_permitted_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::OperationNotPermittedFault.

pub fn is_type_deprecated_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::TypeDeprecatedFault.

pub fn is_unknown_resource_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::UnknownResourceFault.

pub fn is_workflow_execution_already_started_fault(&self) -> bool

Returns true if the error kind is StartWorkflowExecutionError::WorkflowExecutionAlreadyStartedFault.

Trait Implementations

impl CreateUnhandledError for StartWorkflowExecutionError
