Why a template-backed node’s instances could not be merged into one circuit.

Multi-instance emission and Bloq::validate run the same merge. Singleton emission stops after the same structural preflight and translation because merging would change its temporal structure.

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.

DetectorBundle(DetectorBundleError)

A detector bundle use is malformed.

BooleanResource(BooleanResourceError)

Boolean analysis exceeded its configured budget.

MembershipSelectionRequired

Conditional registrations require selector inputs.

MissingMembershipInput(u32)

A required selector input is unavailable.

InvalidMembership(String)

Registration tables violate their structural contract.

UnknownTemplate(TemplateId)

An instance names an absent template.

InvalidBody(BodyId)

A circuit names an absent body.

CyclicBody(BodyId)

Circuit bodies recurse.

MppMeasurementCountMismatch

MPP products and measurement ids have different lengths.

Fields

products: usize

Product count.

measurements: usize

Measurement-id count.

MeasureOutputCountMismatch

Measure targets and outputs have different lengths.

Fields

qubits: usize

Qubit count.

measurements: usize

Measurement-id count.

EmptyMpp

An MPP operation has no products.

EmptyPauliProduct

An MPP product has no Pauli terms.

UnregisteredMeasurementOutput(u32)

An operation produces an unregistered measurement.

DuplicateMeasurementOutput(u32)

Several operations produce the same measurement id.

MeasurementOutputCoordinateMismatch

A measurement registry coordinate disagrees with its operation.

Fields

measurement: u32

Measurement id.

registered: IVec2

Registry coordinate.

produced: IVec2

Operation coordinate.

OddTwoQubitTargetCount

A two-qubit gate has an odd target count.

Fields

gate: GateType

Gate kind.

targets: usize

Target count.

RepeatedTwoQubitGateTarget

A two-qubit gate pair repeats one endpoint.

Fields

gate: GateType

Gate kind.

qubit: IVec2

Repeated endpoint.

OddDepolarize2TargetCount

A two-qubit noise operation has an odd target count.

Fields

targets: usize

Target count.

RepeatedDepolarize2Target(IVec2)

A two-qubit noise pair repeats one endpoint.

InvalidProbability

A probability is non-finite or outside [0, 1].

Fields

instruction: &'static str

Instruction with the invalid probability.

CoordinateOverflow(CoordinateOverflowError)

Coordinate translation overflowed.

MeasurementIdOverflow

Merged measurement ids exhausted u32.

BodyCountOverflow

Circuit-body storage or the merged body-id space exhausted capacity.

NoiseRepeatExpansion(FlattenError)

Repeat expansion for idle noise failed.

TickSegmentCountMismatch

Instance circuits have different tick counts.

RepeatShapeMismatch

A merged segment mixes repeat and non-repeat shapes.

RepeatCountMismatch

Aligned repeats have different counts.

BodyMergeConflict

One body participates in several merge tuples.

Fields

circuit_index: usize

Source circuit index.

body: BodyId

Conflicting body.

QubitConflict(IVec2)

Instance circuits use one qubit incompatibly in a segment.

ControlReferencesUnknownMeasurement(u32)

Conditional feedforward reads a measurement too early.
