Enum CpuTopologyError 

pub enum CpuTopologyError {
    EmptyAllowedCpuSet,
    AffinityUnavailable,
    InvalidCpuList {
        list: String,
        reason: &'static str,
    },
    DuplicateNode {
        node: NumaNodeId,
    },
    OverlappingNodes {
        first: NumaNodeId,
        second: NumaNodeId,
        cpus: CpuSet,
    },
}

Failure to canonicalize discovered NUMA topology.

Examples

use tenferro_cpu::{CpuTopologyError, NumaNodeId};

let error = CpuTopologyError::DuplicateNode { node: NumaNodeId::new(2) };
assert!(error.to_string().contains("2"));

Variants

EmptyAllowedCpuSet

The process affinity mask contained no logical CPU.

AffinityUnavailable

The process CPU affinity mask could not be obtained.

InvalidCpuList

A Linux sysfs CPU-list value was malformed or unreasonably large.

Fields

list: String

The original sysfs CPU-list text.

reason: &'static str

A stable human-readable parsing reason.

DuplicateNode

Discovery reported the same OS NUMA node more than once.

Fields

node: NumaNodeId

The duplicated OS NUMA node ID.

OverlappingNodes

Two usable NUMA nodes contained at least one common logical CPU.

Fields

first: NumaNodeId

The first overlapping OS node ID.

second: NumaNodeId

The second overlapping OS node ID.

cpus: CpuSet

Logical CPUs present in both usable node sets.

Trait Implementations

impl Clone for CpuTopologyError

fn clone(&self) -> CpuTopologyError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpuTopologyError

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

Formats the value using the given formatter.

impl Display for CpuTopologyError

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

Formats the value using the given formatter.

impl Error for CpuTopologyError

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 PartialEq for CpuTopologyError

fn eq(&self, other: &CpuTopologyError) -> 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.
