Enum DescribeScalingPoliciesError 

#[non_exhaustive]
pub enum DescribeScalingPoliciesError {
    ConcurrentUpdateException(ConcurrentUpdateException),
    FailedResourceAccessException(FailedResourceAccessException),
    InternalServiceException(InternalServiceException),
    InvalidNextTokenException(InvalidNextTokenException),
    ValidationException(ValidationException),
    Unhandled(Unhandled),
}

Error type for the DescribeScalingPoliciesError 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.

ConcurrentUpdateException(ConcurrentUpdateException)

Concurrent updates caused an exception, for example, if you request an update to an Application Auto Scaling resource that already has a pending update.

FailedResourceAccessException(FailedResourceAccessException)

Failed access to resources caused an exception. This exception is thrown when Application Auto Scaling is unable to retrieve the alarms associated with a scaling policy due to a client error, for example, if the role ARN specified for a scalable target does not have permission to call the CloudWatch DescribeAlarms on your behalf.

InternalServiceException(InternalServiceException)

The service encountered an internal error.

InvalidNextTokenException(InvalidNextTokenException)

The next token supplied was invalid.

ValidationException(ValidationException)

An exception was thrown for a validation issue. Review the available parameters for the API request.

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 DescribeScalingPoliciesError

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

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

pub fn generic(err: ErrorMetadata) -> Self

Creates the DescribeScalingPoliciesError::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_concurrent_update_exception(&self) -> bool

Returns true if the error kind is DescribeScalingPoliciesError::ConcurrentUpdateException.

pub fn is_failed_resource_access_exception(&self) -> bool

Returns true if the error kind is DescribeScalingPoliciesError::FailedResourceAccessException.

pub fn is_internal_service_exception(&self) -> bool

Returns true if the error kind is DescribeScalingPoliciesError::InternalServiceException.

pub fn is_invalid_next_token_exception(&self) -> bool

Returns true if the error kind is DescribeScalingPoliciesError::InvalidNextTokenException.

pub fn is_validation_exception(&self) -> bool

Returns true if the error kind is DescribeScalingPoliciesError::ValidationException.
