Enum RuntimeError 

#[non_exhaustive]
pub enum RuntimeError {
    IdOverflow(&'static str),
    RegisterAllocation {
        register: &'static str,
        source: TryReserveError,
    },
    InvalidProgram(&'static str),

}

Failures on the dynamic causal runtime path.

That path is run() and the timing, retry, noise, and mock-decoding machinery it drives. The noiseless physical verifier is the other execution engine in this crate and reports ExecError instead.

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.

IdOverflow(&'static str)

A dense runtime or artifact identifier exhausted u32.

RegisterAllocation

A runtime table could not fit or allocate its initial capacity.

Fields

register: &'static str

Runtime table being initialized.

source: TryReserveError

Capacity or allocation failure from the table.

InvalidProgram(&'static str)

A public VM program or runtime setting violated its fixed-register contract.

MissingTask(TaskId)

A task id or dependency was absent.

MissingBit(BitId)

A required classical bit was absent.

MissingRecord(RecordId)

A required record was absent.

StepLimit

The run exhausted its operation-work cap.

Fields

limit: u64

Configured cap.

NoQuantumAlternative

No guarded quantum alternative matched available input bits.

Backend(SimError)

The selected simulator rejected an operation.

Decoder(DecoderError)

Mock decoder configuration or timing was invalid.

InvalidTiming

Finite instruction durations overflowed the runtime clock.

Trait Implementations

impl Debug for RuntimeError

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

Formats the value using the given formatter.

impl Display for RuntimeError

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

Formats the value using the given formatter.

impl Error for RuntimeError

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 From<DecoderError> for RuntimeError

fn from(source: DecoderError) -> Self

Converts to this type from the input type.

impl From<SimError> for RuntimeError

fn from(source: SimError) -> Self

Converts to this type from the input type.
