Function build_collection_codec 

Source 
pub fn build_collection_codec(
    quantization: &str,
    vectors: &[Vec<f32>],
    dim: usize,
    m: usize,
    ef_construction: usize,
    seed: u64,
) -> Option<CollectionCodec>
Expand description

Build a CollectionCodec from a quantization tag and training vectors.

Returns None for unsupported or unrecognised tags (e.g. “sq8”, “pq”, “none”) — those variants use separate per-segment code paths.
