Enum CpuBackendError 

pub enum CpuBackendError {
    Tensor(Error),
    Placement {
        op: &'static str,
        source: CpuPlacementError,
    },
    ExternalRegistry(ExternalCpuDomainRegistryError),
}

Errors returned while constructing a CpuBackend.

Placement failures remain typed so callers can distinguish topology discovery failures from unsupported placement requests. Configuration and provider-selection failures retain the existing tensor error contract.

Examples

use tenferro_cpu::{CpuBackend, CpuBackendError};

let error = CpuBackend::with_threads(0).unwrap_err();
assert!(matches!(error, CpuBackendError::Tensor(_)));

Variants

Tensor(Error)

CPU context configuration or provider selection failed.

Placement

CPU placement resolution or engine construction failed.

Fields

op: &'static str

Constructor that observed the placement failure.

source: CpuPlacementError

Typed placement failure.

ExternalRegistry(ExternalCpuDomainRegistryError)

Externally managed domain registry validation failed.

Implementations

impl CpuBackendError

pub fn placement_error(&self) -> Option<&CpuPlacementError>

Return the typed placement failure, when construction reached placement resolution.

Examples

use tenferro_cpu::{CpuBackend, CpuBackendError};

let result: Result<CpuBackend, CpuBackendError> = CpuBackend::with_threads(1);
if let Err(error) = result {
    let _placement_failure = error.placement_error();
}

Trait Implementations

impl Debug for CpuBackendError

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

Formats the value using the given formatter.

impl Display for CpuBackendError

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

Formats the value using the given formatter.

impl Error for CpuBackendError

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.
