Enum AnyIndex 

pub enum AnyIndex {
    Hnsw(HnswIndex),
    Ivf(IvfIndex),
    ScalarQuantized(ScalarQuantizedIndex),
    BinaryQuantized(BinaryQuantizedIndex),
}

Variants

Hnsw(HnswIndex)

Ivf(IvfIndex)

ScalarQuantized(ScalarQuantizedIndex)

BinaryQuantized(BinaryQuantizedIndex)

Implementations

impl AnyIndex

pub fn from_config(config: &CollectionConfig) -> Self

Construct the correct variant for the given collection config.

Quantization::ScalarInt8 selects the int8 scalar-quantized flat index regardless of index_type (HNSW-over-int8 is not yet implemented); the full-precision on-disk vectors remain authoritative.

pub fn load_or_create( data_dir: &Path, name: &str, config: &CollectionConfig, ) -> (Self, bool)

Load a saved index from data_dir or construct a fresh one. Returns (index, was_loaded_from_disk).

pub fn save_for_collection(&self, data_dir: &Path, name: &str) -> Result<()>

Persist the index to the appropriate file under data_dir.
