Struct FloatScannModel 

pub struct FloatScannModel {
    pub routing: FloatRoutingTree,
    pub codebook: AhCodebook,
    /* private fields */
}

Executable float ScaNN model shared by all immutable segments in one index generation.

Fields

routing: FloatRoutingTree

codebook: AhCodebook

Implementations

impl FloatScannModel

pub fn from_artifact(artifact: &ScannTrainedArtifact) -> ScannResult<Self>

Reconstruct the executable float model from a validated persisted generation. The anisotropic threshold is an implementation invariant, not a schema or artifact knob, so version 1 artifacts use the same hardcoded value as training.

pub fn train( data: &[f32], points: usize, dimension: usize, level_counts: &[u32], dimensions_per_block: usize, iterations: usize, seed: u64, anisotropic_threshold: f32, ) -> ScannResult<(Self, Vec<EncodedFloatVector>)>

pub fn train_model( data: &[f32], points: usize, dimension: usize, level_counts: &[u32], dimensions_per_block: usize, iterations: usize, seed: u64, anisotropic_threshold: f32, ) -> ScannResult<Self>

Train only the index-global model. Production generation training uses this path because training-sample encodings are immediately discarded; immutable segment builders encode the actual corpus later.

pub fn encode(&self, vector: &[f32]) -> ScannResult<EncodedFloatVector>

pub fn encode_with_scratch<'a>( &self, vector: &[f32], scratch: &'a mut FloatEncodeScratch, ) -> ScannResult<(u32, &'a [u8])>

pub fn prepare_query( &self, query: &[f32], probes: usize, ) -> ScannResult<FloatScannQuery>

pub fn anisotropic_threshold(&self) -> f32
