Enum PreparedQuery 

pub enum PreparedQuery {
    Full(Vec<f32>),
    Int8(QuantizedVector),
    Int4(Int4Vector),
    Binary(BinaryVector),
}

Unstable: pre-quantized query for repeated distance computation.

Quantize a query vector once and reuse it against a homogeneous candidate list, eliminating per-call from_f32 overhead. The query tier must match the stored data tier.

Variants

Full(Vec<f32>)

Full f32 query.

Int8(QuantizedVector)

INT8 quantized query.

Int4(Int4Vector)

INT4 packed quantized query.

Binary(BinaryVector)

Binary sign-bit query.

Implementations

impl PreparedQuery

pub fn from_f32(query_f32: &[f32], tier: QuantizationTier) -> Self

Quantize a query at the given tier for repeated distance calls.

pub fn tier(&self) -> QuantizationTier

Returns the quantization tier of this prepared query.

pub fn dims(&self) -> usize

Returns the number of dimensions.
