Failure to construct an externally managed CPU-domain registry.

Examples

use tenferro_cpu::ExternalCpuDomainRegistryError;

let error = ExternalCpuDomainRegistryError::EmptyRegistry;
assert!(error.to_string().contains("at least one"));

Variants

EmptyRegistry

No external domain descriptor was supplied.

DuplicateDomainId

More than one descriptor used the same caller-stable domain ID.

Fields

id: CpuDomainId

Duplicate caller-supplied identity.

DuplicatePlacementIdentity

More than one descriptor claimed the same placement identity.

Fields

placement: CpuPlacement

Duplicate NUMA-node or all-allowed identity.

CpuOutsideAllowedSet

A declared CPU is outside the process-allowed CPU set.

Fields

domain: CpuDomainId

Domain containing the invalid CPU declaration.

cpu: CpuId

CPU absent from the process affinity set.

MissingDefaultDomain

The selected default domain ID was not supplied.

Fields

default_domain: CpuDomainId

Missing caller-selected default identity.

ExactAllAllowedMismatch

An exact all-allowed declaration did not equal the process-allowed set.

Fields

domain: CpuDomainId

Domain with the inconsistent all-allowed declaration.

declared: CpuSet

CPUs declared by the external descriptor.

allowed: CpuSet

CPUs allowed by the current process affinity mask.

Trait Implementations

impl Clone for ExternalCpuDomainRegistryError

fn clone(&self) -> ExternalCpuDomainRegistryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalCpuDomainRegistryError

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

Formats the value using the given formatter.

impl Display for ExternalCpuDomainRegistryError

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

Formats the value using the given formatter.

impl Error for ExternalCpuDomainRegistryError

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<ExternalCpuDomainRegistryError> for CpuBackendError

fn from(source: ExternalCpuDomainRegistryError) -> Self

Converts to this type from the input type.

impl PartialEq for ExternalCpuDomainRegistryError

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
