}

List of possible core errors.

Note that in most cases you don't need to spawn a core error, unless your service is providing some wrapper for core logic and should behave just like core.

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.

IncorrectRuntime

Runtime identifier is incorrect in this context.

UnknownArtifactId

Artifact identifier is unknown.

ArtifactAlreadyDeployed

Artifact with the given identifier is already deployed.

ArtifactNotDeployed

Artifact with the given identifier is not deployed.

ServiceNameExists

Specified service name is already used.

ServiceIdExists

Specified service identifier is already used.

ServiceNotActive

Specified service is not active.

IncorrectInstanceId

Suitable runtime for the given service instance ID is not found.

StackOverflow

Maximum depth of the call stack has been reached.

ServicePending

Service instance is already transitioning to a new status.

InvalidServiceTransition

Requested service transition is invalid given the current service status.

CannotUpgradeService

The artifact to migrate the service to is not a newer version of the current service artifact.

NoMigration

Attempt to rollback or flush migration for a service which has no pending migration.

CannotResumeService

An attempt to resume the service instance with the wrong artifact. The specified artifact has a different name or an inappropriate version.

IncorrectCall

Incorrect call handler: an inner call has returned an error, but it was not propagated.

CannotUnloadArtifact

Cannot unload artifact.

Trait Implementations

impl Clone for CoreError

fn clone(&self) -> CoreError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for CoreError

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 Eq for CoreError

impl ExecutionFail for CoreError

fn kind(&self) -> ErrorKind

Extracts the error kind.

fn description(&self) -> String

Extracts the human-readable error description.

fn with_description(&self, description: impl Display) -> ExecutionError

Creates an error with an externally provided description. The default implementation takes the description as is; implementations can redefine this to wrap it in an error-specific wrapper.

impl From<CoreError> for ExecutionError

fn from(inner: CoreError) -> Self

Performs the conversion.

impl Hash for CoreError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Ord for CoreError

fn cmp(&self, other: &CoreError) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

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

Restrict a value to a certain interval.

impl PartialEq<CoreError> for CoreError

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

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

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl PartialOrd<CoreError> for CoreError

fn partial_cmp(&self, other: &CoreError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use]fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

#[must_use]fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

#[must_use]fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

#[must_use]fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
