Struct IndexSpec 

pub struct IndexSpec {
    pub kind: IndexKind,
    pub pq_subspaces: Option<u32>,
}

Which index a collection uses and how its vectors are compressed (ADR-0007, ADR-0008). Defaults to in-memory HNSW with no quantization (exact search).

Fields

kind: IndexKind

The index structure.

pq_subspaces: Option<u32>

Product-quantization subspaces for quantized kinds (the disk graph, IVF+PQ). None selects a kind-appropriate default or no quantization.

Trait Implementations

impl Clone for IndexSpec

fn clone(&self) -> IndexSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IndexSpec

impl Debug for IndexSpec

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

Formats the value using the given formatter.

impl Default for IndexSpec

fn default() -> IndexSpec

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for IndexSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for IndexSpec

impl PartialEq for IndexSpec

fn eq(&self, other: &IndexSpec) -> 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 IndexSpec

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
