Struct AcornSearchParams 

pub struct AcornSearchParams {
    pub enable: Option<bool>,
    pub max_selectivity: Option<f64>,
}

Fields

enable: Option<bool>

If true, then ACORN may be used for the HNSW search based on filters selectivity.

Improves search recall for searches with multiple low-selectivity payload filters, at cost of performance.

max_selectivity: Option<f64>

Maximum selectivity of filters to enable ACORN.

If estimated filters selectivity is higher than this value, ACORN will not be used. Selectivity is estimated as: estimated number of points satisfying the filters / total number of points.

0.0 for never, 1.0 for always. Default is 0.4.

Implementations

impl AcornSearchParams

pub fn enable(&self) -> bool

Returns the value of enable, or the default value if enable is unset.

pub fn max_selectivity(&self) -> f64

Returns the value of max_selectivity, or the default value if max_selectivity is unset.

Trait Implementations

impl Clone for AcornSearchParams

fn clone(&self) -> AcornSearchParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AcornSearchParams

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

Formats the value using the given formatter.

impl Default for AcornSearchParams

fn default() -> Self

Returns the “default value” for a type.

impl Message for AcornSearchParams

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for AcornSearchParams

fn eq(&self, other: &AcornSearchParams) -> 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.
