Struct PreparedQueryWithMeta 

pub struct PreparedQueryWithMeta {
    pub query: PreparedQuery,
    pub norm: NormalizationHint,
}

A prepared query annotated with a normalization hint for fast-path dispatch.

When norm == NormalizationHint::Unit and the stored vector is also unit-normalized, approximate_cosine_distance_prepared_with_meta skips the norm division and uses 1.0 - dot_product(q, s) directly — recovering ~26% at 384d on the Full tier.

Fields

query: PreparedQuery

The quantized query (owns the data).

norm: NormalizationHint

Caller assertion about the query vector’s normalization state.

Implementations

impl PreparedQueryWithMeta

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

Create a prepared query from an f32 vector, asserting its normalization state.

pub fn tier(&self) -> QuantizationTier

Returns the quantization tier.

pub fn dims(&self) -> usize

Returns the number of dimensions.
