Any failure an oxmera operation can report.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ShapeMismatch

Two shapes were required to match and did not.

Fields

expected: Shape

The shape the operation required.

got: Shape

The shape it received.

op: &'static str

The operation reporting the mismatch.

BroadcastIncompatible

Two shapes cannot broadcast together.

Fields

lhs: Shape

Left operand shape.

rhs: Shape

Right operand shape.

DTypeMismatch

Two dtypes were required to match and did not.

Fields

expected: DType

The dtype the operation required.

got: DType

The dtype it received.

op: &'static str

The operation reporting the mismatch.

UnsupportedDType

An operation does not support a dtype at all.

Fields

dtype: DType

The offending dtype.

op: &'static str

The operation that cannot carry it.

DeviceMismatch

Operands live on different devices.

Fields

lhs: Device

Left operand device.

rhs: Device

Right operand device.

op: &'static str

The operation reporting the mismatch.

IndexOutOfBounds

A logical index was outside a tensor’s bounds.

Fields

index: Vec<usize>

The offending index.

shape: Shape

The shape it was applied to.

RankMismatch

An index had the wrong number of dimensions for the shape.

Fields

index_rank: usize

Rank of the supplied index.

shape_rank: usize

Rank of the shape it was applied to.

BackendUnavailable

No backend is registered for a device.

Fields

device: Device

The device with no backend.

InvalidArgument

An argument was structurally invalid for the operation.

Fields

op: &'static str

The operation.

detail: String

What was wrong with the argument.

Backend

A backend failed internally (driver error, shader compilation, …).

Fields

op: &'static str

The operation.

detail: String

The backend’s own description of the failure.

Io

An I/O failure while loading or saving tensors.

Fields

op: &'static str

The operation.

detail: String

The underlying error, rendered.

NotImplemented

The operation is not implemented for a combination of inputs.

Fields

op: &'static str

The operation.

detail: String

What combination is unsupported.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
