Why a Tier-1 SIMD plan could not be built, started, or advanced; Display renders each with its names.

Variants

OutputNotFound(String)

The selected output does not exist.

DrivingInputNotFound(String)

The driving input does not exist.

DrivingInputNotUsed(String)

The selected output does not depend on the driving input.

OutputPortUnsupported

The selected node has more than one output port.

TooFewMembers

Fewer nodes could be promoted than the plan requires.

Fields

found: usize

Promotable nodes found.

minimum: usize

The minimum required.

NodeIneligible

A node in the cone cannot be promoted.

Fields

node: String

The node.

reason: String

Why it cannot be promoted.

ShapeMismatch

A node changes the lane shape.

Fields

node: String

The node.

BoundaryUnsupported

A node cannot serve as a packet boundary.

Fields

node: String

The node.

BoundaryTypeMismatch

A boundary does not carry the scalar type the plan requires.

Fields

boundary: String

The boundary’s name.

expected: PortType

The scalar type required.

MutableBroadcast(String)

An input other than the driving ordinal is externally writable.

NoneAwareNode(String)

A node accepts None inputs, for which packets have no validity semantics.

OutputModifierUnsupported(String)

The output has a visibility modifier and cannot be packetized speculatively.

ConstOutputUnsupported(String)

The output is an init binding, not a scalar stream.

RuntimeShapeUnsupported(PortType)

The lease driver supports u64 over two i64 lanes only, not this type.

ConstantEvaluationFailed(String)

A constant boundary node could not be evaluated safely.

VectorGraphBuild(String)

The register-typed graph could not be built.

VectorCompilation(String)

The effective native ISA declined the graph.

CapabilityDetection(String)

Native ISA detection failed.

ActiveLease

The previous ordinal lease is not fully drained.

LeaseInputMismatch

The lease targets an input other than the plan’s driving input.

Fields

expected: usize

The plan’s driving input index.

got: usize

The lease’s input index.

LeaseSequenceMismatch

The lease arrived out of reservation order.

Fields

expected: u64

The sequence expected.

got: u64

The sequence received.

LeaseStreamMismatch

The lease’s stream or generation changed within one activation.

ActivationWentBackwards

The activation epoch moved backwards.

Fields

previous: u64

The epoch before.

got: u64

The epoch received.

UnknownBroadcast(String)

The name is not a scope-stable broadcast input of the plan.

BroadcastTypeMismatch

A broadcast value has the wrong type.

Fields

name: String

The broadcast’s name.

expected: PortType

The type expected.

got: PortType

The type received.

Trait Implementations

impl Clone for Tier1SimdError

fn clone(&self) -> Tier1SimdError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tier1SimdError

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

Formats the value using the given formatter.

impl Display for Tier1SimdError

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

Formats the value using the given formatter.

impl Eq for Tier1SimdError

impl Error for Tier1SimdError

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 Tier1SimdError

fn eq(&self, other: &Tier1SimdError) -> bool

Equality operator ==.

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

Inequality operator !=.
