Enum ProjectionRuntimeUnavailabilityReason 

pub enum ProjectionRuntimeUnavailabilityReason {
    None,
    NoRuntime,
    VectorEquivalenceDisabled,
}

The reason ProjectionRuntimeStatus::runtime_embedder_available is false.

This facade is deliberately distinct from the internal lifecycle ProjectionStatus: it describes this open engine session’s ability to run the shared dense pipeline, not the terminal state of a canonical row.

Variants

None

A usable dense runtime is attached, so there is no unavailability.

NoRuntime

This engine session was opened without an attached embedder.

VectorEquivalenceDisabled

The attached embedder failed the existing vector-equivalence guard.
