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.
