Enum EagerError 

pub enum EagerError {
    NoKernel {
        op_type: String,
        domain: String,
        device: DeviceId,
    },
    MixedDeviceInputs {
        devices: Vec<DeviceId>,
        hint: String,
    },
    NoEpForDevice(DeviceId),
    ShapeInference {
        op_type: String,
        domain: String,
        reason: String,
    },
    Kernel(EpError),
    ShapeInferEngine(ShapeInferError),
    Ir(IrError),
}

Errors produced while dispatching a single op in eager mode.

Variants

NoKernel

No EP registered for the resolved device has a kernel for this op at the requested opset (docs/EAGER.md §10.1 step 4).

Fields

op_type: String

domain: String

device: DeviceId

MixedDeviceInputs

Inputs live on more than one device. Eager mode never transfers implicitly (docs/EAGER.md §1.6 / Design Decision): the caller must .to(device) first.

Fields

devices: Vec<DeviceId>

hint: String

NoEpForDevice(DeviceId)

The resolved device has no execution provider registered in the context.

ShapeInference

Per-op output shape/dtype inference is missing or could not resolve to a concrete, allocatable shape (docs/EAGER.md §9). The kernel-provided inference fallback (§9.2) is DEFERRED, so an unresolved output is an error rather than a fall-through.

Fields

op_type: String

domain: String

reason: String

Kernel(EpError)

A lower-layer execution-provider / kernel error (allocation, execution).

ShapeInferEngine(ShapeInferError)

An error escaping the shape-inference engine itself.

Ir(IrError)

An error escaping the IR layer.

Trait Implementations

impl Debug for EagerError

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

Formats the value using the given formatter.

impl Display for EagerError

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

Formats the value using the given formatter.

impl Error for EagerError

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<EpError> for EagerError

fn from(source: EpError) -> Self

Converts to this type from the input type.

impl From<IrError> for EagerError

fn from(source: IrError) -> Self

Converts to this type from the input type.

impl From<ShapeInferError> for EagerError

fn from(source: ShapeInferError) -> Self

Converts to this type from the input type.
