Errors shared by inference contracts and backend adapters.

Variants

DuplicateName(String)

A named input or output appears more than once.

MissingInput(String)

A required model input was not supplied.

UnexpectedTensor(String)

A tensor name is not declared by the model.

DataTypeMismatch

Actual dtype differs from the model contract.

Fields

name: String

Tensor name.

expected: DataType

Model dtype.

actual: DataType

Supplied dtype.

ShapeMismatch

Actual rank or dimension differs from the model contract.

Fields

name: String

Tensor name.

expected: Vec<Dimension>

Model dimensions.

actual: Vec<usize>

Supplied dimensions.

OutputBufferTooSmall

A preallocated output does not have enough bytes.

Fields

name: String

Output name.

required: usize

Required allocation bytes.

found: usize

Available allocation bytes.

Unsupported

The selected backend cannot honor an operation or option.

Fields

backend: String

Backend identifier.

operation: String

Unsupported operation.

Backend

Backend-specific failure with stable outer context.

Fields

backend: String

Backend identifier.

message: String

Backend error message.

InvalidConfiguration(String)

Invalid public configuration.

CopyRequired

A backend would need a copy that the caller did not authorize.

Fields

direction: &'static str

Input or output transfer direction.

name: String

Model-visible tensor name.

Trait Implementations

impl Clone for AiError

fn clone(&self) -> AiError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AiError

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

Formats the value using the given formatter.

impl Display for AiError

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

Formats the value using the given formatter.

impl Error for AiError

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 PartialEq for AiError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
