Error produced while preparing or evaluating a model.

Variants

Execution(ExecutionError)

Execution-context configuration failed.

Memory(MemoryError)

Memory discovery, planning, or reservation failed.

MissingEventScalar(String)

An expression requested an event scalar without an event lookup.

TypeMismatch

An expression node produced an unexpected value type.

Fields

index: usize

Expression-node index.

expected: &'static str

Expected value type.

actual: &'static str

Actual value type.

InvalidShape

An expression node had an invalid shape.

Fields

index: usize

Expression-node index.

message: String

Description of the shape mismatch.

SingularMatrix(usize)

A matrix factorization or solve failed.

InvalidCache

A cache contained the wrong number of slots.

Fields

expected: usize

Expected slot count.

actual: usize

Actual slot count.

InvalidCacheLayout

A cache was created for an incompatible layout.

MissingEventColumn(String)

A required event column was absent from the schema.

Data(String)

Dataset access failed.

Parameter(String)

Parameter validation or lookup failed.

JitExecution(i32)

A JIT-compiled kernel returned a failure status.

Reduction(ReductionError)

A reduction transform failed.

DistributedPeerFailure

Another distributed rank failed during evaluation.

Wgpu(String)

WebGPU preparation or execution failed.

Trait Implementations

impl Clone for RuntimeError

fn clone(&self) -> RuntimeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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<ExecutionError> for RuntimeError

fn from(source: ExecutionError) -> Self

Converts to this type from the input type.

impl From<MemoryError> for RuntimeError

fn from(source: MemoryError) -> Self

Converts to this type from the input type.

impl From<ReductionError> for RuntimeError

fn from(source: ReductionError) -> Self

Converts to this type from the input type.

impl PartialEq for RuntimeError

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

Equality operator ==.

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

Inequality operator !=.
