Struct IndexHandleEntry 

pub struct IndexHandleEntry {
    pub kind: IndexKind,
    pub handle: Arc<dyn IndexHandle>,
}

A live index handle keyed by index name (e.g., "vec_idx_embedding").

Unlike IndexKindProvider, which is plugin-registered via the PluginRegistrar and describes a kind of index, an IndexHandleEntry represents a specific live index — the runtime object produced by IndexKindProvider::build().finalize() (or IndexKindProvider::open()). Handles are inserted by the host (not by the plugin’s register() call) because their lifetime tracks the storage layer rather than plugin metadata.

The planner consults this table by index name when dispatching a vector KNN query (see plan_vector_knn). When Some, the planner routes the probe through the plugin handle; when None, the native storage path runs (preserving the “no behavior change for built-ins” invariant).

Fields

kind: IndexKind

Kind that produced this handle (informational; matches the IndexKindProvider::kind that built it).

handle: Arc<dyn IndexHandle>

The live handle.
