Struct FastScanQuery 

pub struct FastScanQuery { /* private fields */ }

Implementations

impl FastScanQuery

pub fn new(query: &AhQuery) -> Self

pub fn blocks(&self) -> usize

pub fn packed_block_bytes(&self) -> usize

Bytes of one packed 32-row group under this query’s block count.

pub fn is_degenerate(&self) -> bool

True when every AH table was constant (see degenerate).

pub fn accumulate_block( &self, codes: &[u8], scores: &mut [i32; 32], ) -> ScannResult<()>

Integer lane sums for one packed 32-row group; no float conversion.

pub fn lane_score(&self, lane: i32, centroid_dot: f32) -> f32

Convert one integer lane sum into the approximate dot product.

pub fn lane_cutoff(&self, threshold: f32, centroid_dot: f32) -> i32

Largest integer lane sum that can not beat threshold for a row in a leaf with centroid_dot. Lanes <= cutoff may be skipped before any float work; the bound is conservative by one integer step so rounding in multiplier * inverse_multiplier can never drop a competitive row.

pub fn score_block( &self, codes: &[u8], centroid_dot: f32, ) -> ScannResult<[f32; 32]>
