Enum QueryErrorKind 

#[non_exhaustive]
pub enum QueryErrorKind {
    Cancelled,
    Planning,
    InvalidInput,
    Unsupported,
    ResourceExhausted,
    DependencyFailure,
    InvariantViolation,
    Internal,
}

Coarse native-engine error category.

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.

Cancelled

Caller-requested cancellation stopped execution.

Planning

Planning, validation, or IR construction failure.

InvalidInput

Caller-provided input is invalid for the requested operation.

Unsupported

Requested plan, operator, expression, or type is not supported.

ResourceExhausted

Memory or other bounded resource was exhausted or could not be reserved.

DependencyFailure

cuDF or another dependency failed outside resource-exhaustion handling.

InvariantViolation

A native-engine or cuDF invariant was violated.

Internal

Internal bug or unreachable condition.
