Enum ExternalCpuDomainError 

pub enum ExternalCpuDomainError {
    EmptyPlacementCpuSet,
    ZeroExecutorWorkers,
    ThreadBudgetExceedsWorkerCount {
        thread_budget: usize,
        worker_count: usize,
    },
}

Typed failure to construct an externally managed CPU resource domain.

Examples

use tenferro_cpu::ExternalCpuDomainError;

let error = ExternalCpuDomainError::ThreadBudgetExceedsWorkerCount {
    thread_budget: 4,
    worker_count: 2,
};
assert!(error.to_string().contains("4"));

Variants

EmptyPlacementCpuSet

The resolved placement contains no logical CPUs.

ZeroExecutorWorkers

The executor reported no workers.

ThreadBudgetExceedsWorkerCount

The requested thread budget is larger than the executor worker count.

Fields

thread_budget: usize

Requested maximum number of participating threads.

worker_count: usize

Workers reported by the supplied executor.

Trait Implementations

impl Clone for ExternalCpuDomainError

fn clone(&self) -> ExternalCpuDomainError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExternalCpuDomainError

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

Formats the value using the given formatter.

impl Display for ExternalCpuDomainError

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

Formats the value using the given formatter.

impl Error for ExternalCpuDomainError

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 ExternalCpuDomainError

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