Struct aws_sdk_verifiedpermissions::types::error::ValidationException

#[non_exhaustive]
pub struct ValidationException {
    pub message: String,
    pub field_list: Option<Vec<ValidationExceptionField>>,
    /* private fields */
}

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.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

message: String

field_list: Option<Vec<ValidationExceptionField>>

The list of fields that aren't valid.

Implementations

impl ValidationException

pub fn field_list(&self) -> &[ValidationExceptionField]

The list of fields that aren't valid.

If no value was sent for this field, a default will be set. If you want to determine if no value was sent, use .field_list.is_none().

impl ValidationException

pub fn message(&self) -> &str

Returns the error message.

impl ValidationException

pub fn builder() -> ValidationExceptionBuilder

Creates a new builder-style object to manufacture ValidationException.

Trait Implementations

impl Clone for ValidationException

fn clone(&self) -> ValidationException

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ValidationException

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

Formats the value using the given formatter.

impl Display for ValidationException

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

Formats the value using the given formatter.

impl Error for ValidationException

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

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.

impl PartialEq for ValidationException

fn eq(&self, other: &ValidationException) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ProvideErrorMetadata for ValidationException

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 ValidationException

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

Returns the request ID, or None if the service could not be reached.
