Enum BatchGetPolicyError

#[non_exhaustive]
pub enum BatchGetPolicyError {
    AccessDeniedException(AccessDeniedException),
    InternalServerException(InternalServerException),
    ThrottlingException(ThrottlingException),
    ValidationException(ValidationException),
    Unhandled(Unhandled),
}

Error type for the BatchGetPolicyError 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.

AccessDeniedException(AccessDeniedException)

You don't have sufficient access to perform this action.

InternalServerException(InternalServerException)

The request failed because of an internal error. Try your request again later

ThrottlingException(ThrottlingException)

The request failed because it exceeded a throttling quota.

ValidationException(ValidationException)

The request failed because one or more input parameters don't satisfy their constraint requirements. The output is provided as a list of fields and a reason for each field that isn't valid.

The possible reasons include the following:

• UnrecognizedEntityType

  The policy includes an entity type that isn't found in the schema.

• UnrecognizedActionId

  The policy includes an action id that isn't found in the schema.

• InvalidActionApplication

  The policy includes an action that, according to the schema, doesn't support the specified principal and resource.

• UnexpectedType

  The policy included an operand that isn't a valid type for the specified operation.

• IncompatibleTypes

  The types of elements included in a set, or the types of expressions used in an if...then...else clause aren't compatible in this context.

• MissingAttribute

  The policy attempts to access a record or entity attribute that isn't specified in the schema. Test for the existence of the attribute first before attempting to access its value. For more information, see the has (presence of attribute test) operator in the Cedar Policy Language Guide.

• UnsafeOptionalAttributeAccess

  The policy attempts to access a record or entity attribute that is optional and isn't guaranteed to be present. Test for the existence of the attribute first before attempting to access its value. For more information, see the has (presence of attribute test) operator in the Cedar Policy Language Guide.

• ImpossiblePolicy

  Cedar has determined that a policy condition always evaluates to false. If the policy is always false, it can never apply to any query, and so it can never affect an authorization decision.

• WrongNumberArguments

  The policy references an extension type with the wrong number of arguments.

• FunctionArgumentValidationError

  Cedar couldn't parse the argument passed to an extension type. For example, a string that is to be parsed as an IPv4 address can contain only digits and the period character.

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 BatchGetPolicyError

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

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

pub fn generic(err: ErrorMetadata) -> Self

Creates the BatchGetPolicyError::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_access_denied_exception(&self) -> bool

Returns true if the error kind is BatchGetPolicyError::AccessDeniedException.

pub fn is_internal_server_exception(&self) -> bool

Returns true if the error kind is BatchGetPolicyError::InternalServerException.

pub fn is_throttling_exception(&self) -> bool

Returns true if the error kind is BatchGetPolicyError::ThrottlingException.

pub fn is_validation_exception(&self) -> bool

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

Trait Implementations

impl CreateUnhandledError for BatchGetPolicyError

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 BatchGetPolicyError

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

Formats the value using the given formatter.

impl Display for BatchGetPolicyError

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

Formats the value using the given formatter.

impl Error for BatchGetPolicyError

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

impl ProvideErrorMetadata for BatchGetPolicyError

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 BatchGetPolicyError
