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

Instance was not found in the database.

Fields

instance_id: String

The instance ID that was not found.

InstanceAlreadyExists

Instance already exists (duplicate registration).

Fields

instance_id: String

The instance ID that already exists.

InvalidInstanceState

Instance is in an invalid state for the requested operation.

Fields

instance_id: String

The instance ID.

expected: String

The expected status.

actual: String

The actual status.

CheckpointNotFound

Checkpoint was not found.

Fields

instance_id: String

The instance ID.

checkpoint_id: Option<String>

The checkpoint ID that was not found.

CheckpointSaveFailed

Checkpoint save failed.

Fields

instance_id: String

The instance ID.

reason: String

The reason for failure.

SignalDeliveryFailed

Signal delivery failed.

Fields

instance_id: String

The instance ID.

signal_type: String

The signal type that failed.

reason: String

The reason for failure.

ValidationError

Input validation failed.

Fields

field: String

The field that failed validation.

message: String

The validation error message.

DatabaseError

Database operation failed.

Fields

operation: String

Implementations

impl CoreError

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

Get the error code string for this error type.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoreError

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

Formats the value using the given formatter.

impl Display for CoreError

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

Formats the value using the given formatter.

impl Error for CoreError

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<CoreError> for StructuredError

fn from(err: CoreError) -> Self

Converts to this type from the input type.

impl From<Error> for CoreError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CoreError

fn from(err: Error) -> Self
