Struct DynamoDBError 

pub struct DynamoDBError {
    pub code: DynamoDBErrorCode,
    pub message: String,
    pub status_code: StatusCode,
    pub source: Option<Box<dyn Error + Send + Sync>>,
    pub item: Option<HashMap<String, AttributeValue>>,
    pub cancellation_reasons: Vec<CancellationReason>,
}

A DynamoDB error response.

Fields

code: DynamoDBErrorCode

The error code.

message: String

A human-readable error message.

status_code: StatusCode

The HTTP status code.

source: Option<Box<dyn Error + Send + Sync>>

The underlying source error, if any.

item: Option<HashMap<String, AttributeValue>>

The existing item to return in the error response (used by ReturnValuesOnConditionCheckFailure=ALL_OLD).

cancellation_reasons: Vec<CancellationReason>

Cancellation reasons for TransactionCanceledException.

Implementations

impl DynamoDBError

pub fn new(code: DynamoDBErrorCode) -> Self

Create a new DynamoDBError from an error code.

pub fn with_message(code: DynamoDBErrorCode, message: impl Into<String>) -> Self

Create a new DynamoDBError with a custom message.

pub fn with_source(self, source: impl Error + Send + Sync + 'static) -> Self

Set the source error.

pub fn with_item(self, item: HashMap<String, AttributeValue>) -> Self

Attach an existing item to the error response (for ReturnValuesOnConditionCheckFailure=ALL_OLD).

pub fn with_cancellation_reasons(self, reasons: Vec<CancellationReason>) -> Self

Attach cancellation reasons to a TransactionCanceledException.

pub fn error_type(&self) -> &'static str

Returns the __type string for the JSON error response.

pub fn resource_in_use(message: impl Into<String>) -> Self

Table already exists.

pub fn resource_not_found(message: impl Into<String>) -> Self

Table or resource not found.

pub fn conditional_check_failed(message: impl Into<String>) -> Self

Condition expression evaluated to false.

pub fn validation(message: impl Into<String>) -> Self

Validation error.

pub fn serialization_exception(message: impl Into<String>) -> Self

Serialization error.

pub fn internal_error(message: impl Into<String>) -> Self

Internal server error.

pub fn missing_action() -> Self

Missing action header.

pub fn transaction_cancelled(reasons: Vec<CancellationReason>) -> Self

pub fn unknown_operation(target: &str) -> Self

Unknown operation.

Trait Implementations

impl Debug for DynamoDBError

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

Formats the value using the given formatter.

impl Display for DynamoDBError

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

Formats the value using the given formatter.

impl Error for DynamoDBError

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

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
