Enum GetInstanceError 

#[non_exhaustive]
pub enum GetInstanceError {
    InstanceNotFound(InstanceNotFound),
    InvalidInput(InvalidInput),
    ServiceNotFound(ServiceNotFound),
    Unhandled(Unhandled),
}

Error type for the GetInstanceError 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.

InstanceNotFound(InstanceNotFound)

No instance exists with the specified ID, or the instance was recently registered, and information about the instance hasn't propagated yet.

InvalidInput(InvalidInput)

One or more specified values aren't valid. For example, a required value might be missing, a numeric value might be outside the allowed range, or a string value might exceed length constraints.

ServiceNotFound(ServiceNotFound)

No service exists with the specified ID.

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 GetInstanceError

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

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

pub fn generic(err: ErrorMetadata) -> Self

Creates the GetInstanceError::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_instance_not_found(&self) -> bool

Returns true if the error kind is GetInstanceError::InstanceNotFound.

pub fn is_invalid_input(&self) -> bool

Returns true if the error kind is GetInstanceError::InvalidInput.

pub fn is_service_not_found(&self) -> bool

Returns true if the error kind is GetInstanceError::ServiceNotFound.

Trait Implementations

impl CreateUnhandledError for GetInstanceError

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 GetInstanceError

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

Formats the value using the given formatter.

impl Display for GetInstanceError

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

Formats the value using the given formatter.

impl Error for GetInstanceError

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.

impl From<GetInstanceError> for Error

fn from(err: GetInstanceError) -> Self

Converts to this type from the input type.

impl ProvideErrorKind for GetInstanceError

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

Returns the code for this error if one exists

fn retryable_error_kind(&self) -> Option<ErrorKind>

Returns the ErrorKind when the error is modeled as retryable

impl ProvideErrorMetadata for GetInstanceError

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 GetInstanceError

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

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