Enum ErrorKind 

#[non_exhaustive]
pub enum ErrorKind {
    InvalidInput,
    NotFound,
    Unsupported,
    ExecutionContext,
    ResourceExhausted,
    DependencyFailure,
    InvariantViolation,
}

Coarse failure category, derived from ErrorCode via kind_for_code.

ErrorKind exists for caller policy that needs only the broad category. Error does not store it; each call projects it from code.

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.

InvalidInput

The caller provided invalid values, schema requests, or foreign inputs.

NotFound

A named resource referenced by the caller does not exist.

Unsupported

The requested dtype, layout, or operation is not supported.

ExecutionContext

A runtime, readiness, provenance, or execution binding contract failed.

ResourceExhausted

The operation ran out of memory or another bounded resource.

DependencyFailure

A lower-layer CUDA, I/O, or foreign dependency failed.

InvariantViolation

An invariant was violated (domestic or foreign).
