Struct VectorPrimaryConfig 

pub struct VectorPrimaryConfig {
    pub vector_field: String,
    pub dim: u32,
    pub quantization: VectorQuantization,
    pub m: u8,
    pub ef_construction: u16,
    pub metric: DistanceMetric,
    pub payload_indexes: Vec<(String, PayloadIndexKind)>,
}

Configuration for a vector-primary collection.

Stored in StoredCollection::vector_primary when primary == PrimaryEngine::Vector. All options correspond to HNSW construction parameters and codec selection for the primary vector index.

Fields

vector_field: String

The name of the column that holds vector data (must be of type VECTOR(n)).

dim: u32

Vector dimensionality.

quantization: VectorQuantization

Quantization codec for the primary HNSW index.

m: u8

HNSW M parameter (number of connections per node).

ef_construction: u16

HNSW ef_construction parameter (beam width during index construction).

metric: DistanceMetric

Distance metric used for similarity search.

payload_indexes: Vec<(String, PayloadIndexKind)>

Payload field names that receive in-memory bitmap indexes for fast pre-filtering, paired with the storage kind (Equality / Range / Boolean). The DDL handler infers the kind from the column type: numeric / timestamp / decimal → Range; bool → Boolean; everything else → Equality.

Trait Implementations

impl Clone for VectorPrimaryConfig

fn clone(&self) -> VectorPrimaryConfig

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VectorPrimaryConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VectorPrimaryConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for VectorPrimaryConfig

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'__msgpack_de> FromMessagePack<'__msgpack_de> for VectorPrimaryConfig

fn read<R: Read<'__msgpack_de>>(reader: &mut R) -> Result<Self, Error>

where Self: Sized,

Reads the MessagePack representation of this value from the provided reader.

impl PartialEq for VectorPrimaryConfig

fn eq(&self, other: &VectorPrimaryConfig) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for VectorPrimaryConfig

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToMessagePack for VectorPrimaryConfig

fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the MessagePack representation of this value into the provided writer.
