Enum GetActivityTaskError

#[non_exhaustive]
pub enum GetActivityTaskError {
    ActivityDoesNotExist(ActivityDoesNotExist),
    ActivityWorkerLimitExceeded(ActivityWorkerLimitExceeded),
    InvalidArn(InvalidArn),
    KmsAccessDeniedException(KmsAccessDeniedException),
    KmsInvalidStateException(KmsInvalidStateException),
    KmsThrottlingException(KmsThrottlingException),
    Unhandled(Unhandled),
}

Error type for the GetActivityTaskError 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.

ActivityDoesNotExist(ActivityDoesNotExist)

The specified activity does not exist.

ActivityWorkerLimitExceeded(ActivityWorkerLimitExceeded)

The maximum number of workers concurrently polling for activity tasks has been reached.

InvalidArn(InvalidArn)

The provided Amazon Resource Name (ARN) is not valid.

KmsAccessDeniedException(KmsAccessDeniedException)

Either your KMS key policy or API caller does not have the required permissions.

KmsInvalidStateException(KmsInvalidStateException)

The KMS key is not in valid state, for example: Disabled or Deleted.

KmsThrottlingException(KmsThrottlingException)

Received when KMS returns ThrottlingException for a KMS call that Step Functions makes on behalf of the caller.

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 GetActivityTaskError

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

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

pub fn generic(err: ErrorMetadata) -> Self

Creates the GetActivityTaskError::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_activity_does_not_exist(&self) -> bool

Returns true if the error kind is GetActivityTaskError::ActivityDoesNotExist.

pub fn is_activity_worker_limit_exceeded(&self) -> bool

Returns true if the error kind is GetActivityTaskError::ActivityWorkerLimitExceeded.

pub fn is_invalid_arn(&self) -> bool

Returns true if the error kind is GetActivityTaskError::InvalidArn.

pub fn is_kms_access_denied_exception(&self) -> bool

Returns true if the error kind is GetActivityTaskError::KmsAccessDeniedException.

pub fn is_kms_invalid_state_exception(&self) -> bool

Returns true if the error kind is GetActivityTaskError::KmsInvalidStateException.

pub fn is_kms_throttling_exception(&self) -> bool

Returns true if the error kind is GetActivityTaskError::KmsThrottlingException.

Trait Implementations

impl CreateUnhandledError for GetActivityTaskError

fn create_unhandled_error( source: Box<dyn Error + Send + Sync + 'static>, meta: Option<ErrorMetadata>, ) -> Self

Creates an unhandled error variant with the given source and error metadata.

impl Debug for GetActivityTaskError

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

Formats the value using the given formatter.
