Index definition for a model.

Fields

name: Option<SmolStr>

Index name (auto-generated if not specified).

fields: Vec<IndexField>

Fields included in the index.

is_unique: bool

Whether this is a unique index.

index_type: Option<IndexType>

Index type (btree, hash, etc.).

vector_ops: Option<VectorOps>

Vector distance operation (for HNSW/IVFFlat indexes).

hnsw_m: Option<u32>

HNSW m parameter (max connections per layer, default 16).

hnsw_ef_construction: Option<u32>

HNSW ef_construction parameter (size of candidate list during build, default 64).

ivfflat_lists: Option<u32>

IVFFlat lists parameter (number of inverted lists, default 100).
