CapabilityNotHeld(PluginId, CapId)

Plugin does not hold capability (plugin, cap)

IsolationViolation(PluginId, PluginId)

Isolation violation (active, affected)

DanglingCapability(MemAddr)

Dangling capability would result from freeing this address

PluginExists(PluginId)

Plugin already exists

ActorExists(ActorId)

Actor already exists

ResourceExists(ResourceId)

Trait Implementations

impl Debug for StateError

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

Formats the value using the given formatter.

impl Display for StateError

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

Formats the value using the given formatter.

impl Error for StateError

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<StateError> for Error

fn from(e: StateError) -> Self

Converts to this type from the input type.

impl From<StateError> for StepError

fn from(e: StateError) -> Self

Converts to this type from the input type.
