Top-level error type for PRISM-Q operations.

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.

Parse

OpenQASM parse error with source line number.

Fields

line: usize

message: String

UnsupportedConstruct

Valid OpenQASM that PRISM-Q does not support. A loop keyword names the entry point that reads it.

Fields

construct: String

line: usize

InvalidQubit

Qubit index exceeds register size.

Fields

index: usize

register_size: usize

InvalidClassicalBit

Classical bit index exceeds register size.

Fields

index: usize

register_size: usize

GateArity

Gate applied to wrong number of qubits.

Fields

gate: String

expected: usize

got: usize

BackendUnsupported

Backend does not support the requested operation.

Fields

backend: String

operation: String

InvalidParameter

Invalid gate parameter (e.g., NaN rotation angle).

Fields

message: String

UndefinedRegister

Reference to a register name that was never declared.

Fields

name: String

line: usize

ExportUnsupported

Circuit holds an instruction with no OpenQASM 3.0 spelling.

Fields

index: usize

reason: String

IncompatibleBackend

Incompatible backend for the given circuit.

Fields

backend: String

reason: String

StepLimit

A shot of a dynamic program ran more blocks than its step bound allows. region names the loop it was in.

Fields

region: String

max_steps: u64

ResourceLimit(Box<ResourceLimit>)

An allocation the run needs is over a memory cap; the numbers are on ResourceLimit, boxed so the error stays small on every Result.

Trait Implementations

impl Clone for PrismError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrismError

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

Formats the value using the given formatter.

impl Display for PrismError

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

Formats the value using the given formatter.

impl Error for PrismError

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 PrismError

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

Equality operator ==.

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

Inequality operator !=.
