Enum CpuProviderDomainError 

pub enum CpuProviderDomainError {
    ThreadCountNotEnforceable {
        thread_budget: usize,
        control: CpuThreadCountControl,
    },
    PlacementNotEnforceable {
        thread_budget: usize,
        placement: CpuPlacementControl,
        guarantee: CpuPlacementGuarantee,
    },
    ParallelModeNotSupported {
        mode: ParallelMode,
    },
}

Typed incompatibility between a CPU provider and a selected CPU domain.

Examples

use tenferro_cpu::{CpuProviderDomainError, CpuThreadCountControl};
let error = CpuProviderDomainError::ThreadCountNotEnforceable {
    thread_budget: 4,
    control: CpuThreadCountControl::GlobalOrUncontrolled,
};
assert!(error.to_string().contains("thread budget 4"));

Variants

ThreadCountNotEnforceable

The provider cannot enforce the domain’s per-call thread upper bound.

Fields

thread_budget: usize

Requested maximum number of participating threads.

control: CpuThreadCountControl

Provider thread-count classification.

PlacementNotEnforceable

The provider cannot enforce the domain’s placement guarantee.

Fields

thread_budget: usize

Requested maximum number of participating threads.

placement: CpuPlacementControl

Provider placement classification.

guarantee: CpuPlacementGuarantee

Placement guarantee requested by the domain.

ParallelModeNotSupported

The provider cannot honor the engine-selected fan-out mode.

Fields

mode: ParallelMode

Mode selected by the execution engine.

Trait Implementations

impl Clone for CpuProviderDomainError

fn clone(&self) -> CpuProviderDomainError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpuProviderDomainError

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

Formats the value using the given formatter.

impl Display for CpuProviderDomainError

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

Formats the value using the given formatter.

impl Error for CpuProviderDomainError

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 CpuProviderDomainError

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