Enum IndexType 

pub enum IndexType {
    Hnsw(HnswConfig),
    IvfPq(IvfPqConfig),
    Auto,
}

Which index algorithm to embed in the AILK section.

Variants

Hnsw(HnswConfig)

HNSW (default). Best recall for in-memory workloads.

IvfPq(IvfPqConfig)

IVF-PQ. Best for S3: 10-100x smaller index, sequential inverted-list reads.

Auto

Detect hardware at write time and pick the best index automatically.

Chooses IVF-PQ when a GPU or ≥8 CPU cores are available AND the dataset has ≥5 000 vectors. Falls back to HNSW otherwise (local/low-power hardware).

Trait Implementations

impl Clone for IndexType

fn clone(&self) -> IndexType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexType

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

Formats the value using the given formatter.

impl Default for IndexType

fn default() -> Self

Returns the “default value” for a type.
