A source/realization mismatch, unsupported contract, or inference limit.

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.

Qasm(QasmError)

Neutral QASM parsing or validation failed.

Graph(BlockGraphError)

Block-graph construction or validation failed.

Verify(VerifyLogicalError)

Logical map verification failed.

RuntimeBasis(RuntimeBasisError)

Runtime-basis construction or update failed.

OutputCorrection(OutputCorrectionError)

Output correction surfaces could not be solved.

Binding(String)

Caller-supplied source/graph correspondence is invalid.

Limit

Inference exceeded an explicit resource limit.

Fields

phase: &'static str

Bounded inference phase or resource name.

observed: usize

Resource amount required or observed.

limit: usize

Configured maximum.

IncompleteCertificate

Anonymous outcomes do not span the expected boundary space.

Fields

rank: usize

Observed independent boundary rank.

expected: usize

Required boundary rank.

RejectionMismatch

Source and realization disagree on whether a branch is rejected.

Fields

assignment: BranchAssignment

Named outcome assignment selecting the branch.

SupportMismatch

Source and realization disagree on whether a branch map is nonzero.

Fields

assignment: BranchAssignment

Named outcome assignment selecting the branch.

NoOutputPauli

No output Pauli relates one realization branch to its source branch.

Fields

assignment: BranchAssignment

Named outcome assignment selecting the branch.

NoPauliFeedback

Internal Pauli trials found no correction satisfying all branches.

Fields

trials: usize

Number of internal candidate trials performed.

EmissionMismatch

Rechecking the emitted feedback disagreed with the inferred correction.

EmptyDomain

The comparison has no admitted nonzero branch.

NonFiniteTensor

QuiZX tensor arithmetic produced a NaN or infinity.

ArithmeticLimit

Checked dyadic arithmetic overflowed or lost exactness.

ReadoutConventionUnavailable(String)

Existing readouts do not establish a signed C0 convention.

Trait Implementations
