Enum ScoringFunction 

pub enum ScoringFunction {
    DotProduct,
    Bm25 {
        k1_times_10: u8,
        b_times_100: u8,
    },
}

Scoring function for sparse vector similarity.

Variants

DotProduct

Dot product: sum of query_weight * doc_weight for matching tokens.

Bm25

BM25-style scoring with length normalization.

Fields

k1_times_10: u8

BM25 k1 parameter (default: 1.2).

b_times_100: u8

BM25 b parameter (default: 0.75).

Implementations

impl ScoringFunction

pub const fn bm25() -> Self

Create BM25 scoring with default parameters.

pub fn bm25_custom(k1: f32, b: f32) -> Self

Create BM25 scoring with custom parameters.

Trait Implementations

impl Clone for ScoringFunction

fn clone(&self) -> ScoringFunction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScoringFunction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ScoringFunction

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScoringFunction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScoringFunction

fn eq(&self, other: &ScoringFunction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ScoringFunction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ScoringFunction

impl Eq for ScoringFunction

impl StructuralPartialEq for ScoringFunction
