Plugin not found

ActorNotFound(PluginId)

Actor not found

AddressAlreadyFreed(MemAddr)

Memory address already freed (double-free prevention)

CapabilityTargetsAddress(CapId, MemAddr)

Capability targets this address (temporal safety violation)

CapabilityNotFound(CapId)

Capability not found

AuthorizationFailed(AuthorizationError)

Authorization failed

PluginPreconditionFailed(PluginPrecondition)

Plugin precondition failed

HostCallPreconditionFailed(HostCallPrecondition)

Host call precondition failed

KernelOpFailed(KernelOpError)

Kernel operation failed

InvalidTransition(InvalidTransitionReason)

Invalid state transition

StateError(StateError)

State operation failed

QuotaExceeded(u8, u64, u64, u64)

Resource quota exceeded (DoS prevention)

Trait Implementations

impl Debug for StepError

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

Formats the value using the given formatter.

impl Display for StepError

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

Formats the value using the given formatter.

impl Error for StepError

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.
