Enum qdrant_client::qdrant::RecommendStrategy

#[repr(i32)]
pub enum RecommendStrategy {
    AverageVector = 0,
    BestScore = 1,
}

How to use positive and negative vectors to find the results, default is AverageVector:

Variants

AverageVector = 0

Average positive and negative vectors and create a single query with the formula query = avg_pos + avg_pos - avg_neg. Then performs normal search.

BestScore = 1

Uses custom search objective. Each candidate is compared against all examples, its score is then chosen from the max(max_pos_score, max_neg_score). If the max_neg_score is chosen then it is squared and negated.

Implementations

impl RecommendStrategy

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of RecommendStrategy.

pub fn from_i32(value: i32) -> Option<RecommendStrategy>

👎Deprecated: Use the TryFrom<i32> implementation instead

Converts an i32 to a RecommendStrategy, or None if value is not a valid variant.

impl RecommendStrategy

pub fn as_str_name(&self) -> &'static str

String value of the enum field names used in the ProtoBuf definition.

The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

pub fn from_str_name(value: &str) -> Option<Self>

Creates an enum from field names used in the ProtoBuf definition.

Trait Implementations

impl Clone for RecommendStrategy

fn clone(&self) -> RecommendStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RecommendStrategy

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

Formats the value using the given formatter.

impl Default for RecommendStrategy

fn default() -> RecommendStrategy

Returns the “default value” for a type.

impl From<RecommendStrategy> for i32

fn from(value: RecommendStrategy) -> i32

Converts to this type from the input type.

impl Hash for RecommendStrategy

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for RecommendStrategy

fn cmp(&self, other: &RecommendStrategy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for RecommendStrategy

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for RecommendStrategy

fn partial_cmp(&self, other: &RecommendStrategy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl TryFrom<i32> for RecommendStrategy

type Error = DecodeError

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<RecommendStrategy, DecodeError>

Performs the conversion.
