Struct HnswConfigDiff

pub struct HnswConfigDiff {
    pub m: Option<u64>,
    pub ef_construct: Option<u64>,
    pub full_scan_threshold: Option<u64>,
    pub max_indexing_threads: Option<u64>,
    pub on_disk: Option<bool>,
    pub payload_m: Option<u64>,
}

Fields

m: Option<u64>

Number of edges per node in the index graph. Larger the value - more accurate the search, more space required.

ef_construct: Option<u64>

Number of neighbours to consider during the index building. Larger the value - more accurate the search, more time required to build the index.

full_scan_threshold: Option<u64>

Minimal size (in KiloBytes) of vectors for additional payload-based indexing. If the payload chunk is smaller than full_scan_threshold additional indexing won’t be used - in this case full-scan search should be preferred by query planner and additional indexing is not required. Note: 1 Kb = 1 vector of size 256

max_indexing_threads: Option<u64>

Number of parallel threads used for background index building. If 0 - auto selection.

on_disk: Option<bool>

Store HNSW index on disk. If set to false, the index will be stored in RAM.

payload_m: Option<u64>

Number of additional payload-aware links per node in the index graph. If not set - regular M parameter will be used.

Implementations

impl HnswConfigDiff

pub fn m(&self) -> u64

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

pub fn ef_construct(&self) -> u64

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

pub fn full_scan_threshold(&self) -> u64

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

pub fn max_indexing_threads(&self) -> u64

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

pub fn on_disk(&self) -> bool

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

pub fn payload_m(&self) -> u64

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

Trait Implementations

impl Clone for HnswConfigDiff

fn clone(&self) -> HnswConfigDiff

Returns a copy of the value.

fn default() -> Self

Returns the “default value” for a type.

impl Message for HnswConfigDiff

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

impl PartialEq for HnswConfigDiff

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