Enum CpuAffinityError 

pub enum CpuAffinityError {
    CpuSet(CpuSetError),
    Set {
        source: Error,
    },
    Query {
        source: Error,
    },
    UnsupportedPlatform,
    VerificationUnavailable,
    Verification {
        observed: Vec<CpuId>,
    },
    MaskSizeOverflow,
    MaskTooLarge {
        cpu: CpuId,
        max_bytes: usize,
    },
    MaskAllocation {
        source: TryReserveError,
    },
    EmptyMask,
}

Typed failures from the operating-system CPU-affinity boundary.

These errors stay CPU-local until a context-construction failure is reported to the tensor API, where the complete value is retained as the source of crate::CpuContextError.

Examples

use tenferro_cpu::CpuAffinityError;

let error = CpuAffinityError::UnsupportedPlatform;
assert!(error.to_string().contains("unsupported"));

Variants

CpuSet(CpuSetError)

Constructing the one-CPU mask failed because the CPU set was invalid.

Set

The operating system rejected the requested affinity mask.

Fields

source: Error

Query

Querying the current worker affinity failed.

Fields

source: Error

UnsupportedPlatform

The platform has no supported thread-affinity implementation.

VerificationUnavailable

The operating system did not expose a process affinity mask.

Verification

The returned affinity did not contain exactly the requested worker.

Fields

observed: Vec<CpuId>

MaskSizeOverflow

The requested CPU would overflow the affinity-mask size calculation.

MaskTooLarge

The requested CPU exceeds the supported mask allocation limit.

Fields

cpu: CpuId

max_bytes: usize

MaskAllocation

Allocating the operating-system affinity mask failed.

Fields

source: TryReserveError

EmptyMask

The affinity mask had no CPU entries.

Trait Implementations

impl Debug for CpuAffinityError

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

Formats the value using the given formatter.

impl Display for CpuAffinityError

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

Formats the value using the given formatter.

impl Error for CpuAffinityError

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<CpuSetError> for CpuAffinityError

fn from(source: CpuSetError) -> Self

Converts to this type from the input type.
