Errors produced by the rule registry.

Variants

NotFound(String)

No such rule in the registry.

VersionDowngrade

Incoming version is not strictly newer than the current active version.

Fields

current: u64

Currently active version.

proposed: u64

Version the caller tried to install.

ComputeCapMismatch

Rule targets a compute capability the device does not meet.

Fields

required: String

Compute cap the rule requires.

available: String

Compute cap the device actually has.

MissingDependency(String)

Rule depends on another rule that is not registered.

InvalidSignature

Signature check did not succeed.

RollbackTargetMissing(u64)

Caller asked to roll back to a version no longer in history.

NoActiveVersion

No version is currently active — nothing to roll back from.

QuiesceTimeout(Duration)

Quiesce window elapsed before the actor finished draining.

BackendError(String)

Swap backend refused the operation (wraps backend-specific detail).

DuplicateVersion

Version was already registered and we do not allow re-register of the same (rule_id, version) tuple.

Fields

rule_id: String

Rule identifier.

version: u64

Version that was already present.

Trait Implementations

impl Debug for RuleError

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

Formats the value using the given formatter.

impl Display for RuleError

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

Formats the value using the given formatter.

impl Error for RuleError

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.
