Error produced while resolving execution options.

Variants

ZeroThreads

A fixed thread policy requested zero threads.

ThreadPool(String)

A CPU worker pool could not be constructed.

UnsupportedCpuF32Model

The model cannot currently execute on the 32-bit CPU path.

UnsupportedCpuF32Gradient

CPU gradients are not available at 32-bit precision.

GpuUnavailable(GpuBackend)

The requested GPU implementation is unavailable.

UnsupportedGpuGradient

GPU gradients are not currently available.

UnsupportedReverseAutodiff

The requested reverse-mode configuration is unsupported.

JitUnavailable

JIT execution was requested without the jit feature.

Trait Implementations

impl Clone for ExecutionError

fn clone(&self) -> ExecutionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Eq for ExecutionError

impl Error for ExecutionError

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 From<ExecutionError> for RuntimeError

fn from(source: ExecutionError) -> Self

Converts to this type from the input type.

impl PartialEq for ExecutionError

fn eq(&self, other: &ExecutionError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
