Enum aws_sdk_dynamodb::operation::scan::ScanError

#[non_exhaustive]
pub enum ScanError {
    InternalServerError(InternalServerError),
    InvalidEndpointException(InvalidEndpointException),
    ProvisionedThroughputExceededException(ProvisionedThroughputExceededException),

    ResourceNotFoundException(ResourceNotFoundException),
    Unhandled(Unhandled),
}

Error type for the ScanError 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.

InternalServerError(InternalServerError)

An error occurred on the server side.

InvalidEndpointException(InvalidEndpointException)

ProvisionedThroughputExceededException(ProvisionedThroughputExceededException)

Your request rate is too high. The Amazon Web Services SDKs for DynamoDB automatically retry requests that receive this exception. Your request is eventually successful, unless your retry queue is too large to finish. Reduce the frequency of requests and use exponential backoff. For more information, go to Error Retries and Exponential Backoff in the Amazon DynamoDB Developer Guide.

RequestLimitExceeded(RequestLimitExceeded)

Throughput exceeds the current throughput quota for your account. Please contact Amazon Web Services Support to request a quota increase.

ResourceNotFoundException(ResourceNotFoundException)

The operation tried to access a nonexistent table or index. The resource might not be specified correctly, or its status might not be ACTIVE.

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 ScanError

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

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

pub fn generic(err: ErrorMetadata) -> Self

Creates the ScanError::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_internal_server_error(&self) -> bool

Returns true if the error kind is ScanError::InternalServerError.

pub fn is_invalid_endpoint_exception(&self) -> bool

Returns true if the error kind is ScanError::InvalidEndpointException.

pub fn is_provisioned_throughput_exceeded_exception(&self) -> bool

Returns true if the error kind is ScanError::ProvisionedThroughputExceededException.

pub fn is_request_limit_exceeded(&self) -> bool

Returns true if the error kind is ScanError::RequestLimitExceeded.

pub fn is_resource_not_found_exception(&self) -> bool

Returns true if the error kind is ScanError::ResourceNotFoundException.

Trait Implementations

impl CreateUnhandledError for ScanError

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 ScanError

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

Formats the value using the given formatter.

impl Display for ScanError

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

Formats the value using the given formatter.

impl Error for ScanError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn description(&self) -> &str

impl ProvideErrorMetadata for ScanError

fn meta(&self) -> &ErrorMetadata

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

fn code(&self) -> Option<&str>

Returns the error code if it’s available.

fn message(&self) -> Option<&str>

Returns the error message, if there is one.

impl RequestId for ScanError
