Enum DistanceType 

pub enum DistanceType {
    Semantic,
    Absolute,
    Relative,
    Exact,
    Overlap,
}

Distance/similarity type for fields

Variants

Semantic

Trigram similarity for text fields

Absolute

Absolute distance: exp(-|a - b| / scale)

Relative

Relative distance: 1 - |a - b| / max(|a|, |b|)

Exact

Exact match: 1 if equal, 0 otherwise

Overlap

Overlap/Jaccard similarity for token sets

Trait Implementations

impl Clone for DistanceType

fn clone(&self) -> DistanceType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DistanceType

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

Formats the value using the given formatter.

impl Default for DistanceType

fn default() -> DistanceType

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DistanceType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DistanceType

fn eq(&self, other: &DistanceType) -> 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 DistanceType

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 DistanceType

impl Eq for DistanceType

impl StructuralPartialEq for DistanceType
