Errors produced while constructing or validating kernel IR.

Variants

Empty

The IR contained no values.

RootOutOfBounds

The scalar root identifier was outside the value array.

Fields

root: usize

Invalid root index.

len: usize

Number of IR values.

GradientOutOfBounds

A gradient output identifier was outside the value array.

Fields

output: usize

Invalid output index.

len: usize

Number of IR values.

EmptyCacheOutputs

A cache kernel had no outputs.

CacheOutputOutOfBounds

A cache output identifier was outside the value array.

Fields

output: usize

Invalid output index.

len: usize

Number of IR values.

GradientKindMismatch

A gradient output was not real-valued.

Fields

output: usize

Output index.

actual: KernelValueKind

Actual output kind.

InvalidOperand

An instruction referenced a value that did not precede it.

Fields

value: usize

Index of the invalid instruction.

operand: usize

Invalid operand index.

EmptyOperands

An instruction requiring operands was empty.

Fields

value: usize

Index of the invalid instruction.

operation: &'static str

Operation being validated.

KindMismatch

A value’s declared kind did not match its instruction.

Fields

value: usize

Index of the invalid value.

expected: KernelValueKind

Kind produced by the instruction.

actual: KernelValueKind

Declared kind.

ClassMismatch

A value’s declared evaluation class did not match its dependencies.

Fields

value: usize

Index of the invalid value.

expected: KernelValueClass

Class required by the dependencies.

actual: KernelValueClass

Declared class.

InvalidShape

Operand shapes were incompatible with an instruction.

Fields

value: usize

Index of the invalid value.

operation: &'static str

Operation being validated.

message: String

Description of the incompatibility.

Trait Implementations

impl Clone for KernelError

fn clone(&self) -> KernelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KernelError

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

Formats the value using the given formatter.

impl Display for KernelError

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

Formats the value using the given formatter.

impl Eq for KernelError

impl Error for KernelError

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 KernelError

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

Equality operator ==.

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

Inequality operator !=.
