    TooManyWorkers {
        workers: usize,
        cpus: usize,
    },
    PoolBuild {

}

Failure to construct a CPU context with pinned Rayon workers.

Examples

use tenferro_cpu::CpuContextError;

let error = CpuContextError::InvalidThreadCount;
assert!(error.to_string().contains("thread count"));

Variants

InvalidThreadCount

A context must contain at least one worker.

TooManyWorkers

A pinned engine cannot create more workers than assigned CPUs.

Fields

workers: usize

Requested Rayon worker count.

cpus: usize

Number of logical CPUs in the execution domain.

PoolBuild

Rayon could not construct the custom thread pool.

Fields

source: ThreadPoolBuildError

Rayon or OS thread-spawn error.

WorkerPinning

A worker could not set or verify its assigned CPU affinity.

Fields

worker: usize

Stable Rayon worker index.

cpu: CpuId

Assigned operating-system logical CPU.

source: CpuAffinityError

OS or verification failure.

WorkerStartupClosed

A worker terminated before reporting startup affinity.

Fields

source: RecvError

Channel receive failure from the worker startup handshake.

Trait Implementations

impl Debug for CpuContextError

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

Formats the value using the given formatter.

impl Display for CpuContextError

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

Formats the value using the given formatter.

impl Error for CpuContextError

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.
