Struct VectorAnnOptions 

pub struct VectorAnnOptions {
    pub quantization: Option<VectorQuantization>,
    pub oversample: Option<u8>,
    pub query_dim: Option<u32>,
    pub meta_token_budget: Option<u8>,
    pub ef_search_override: Option<usize>,
    pub target_recall: Option<f32>,
}

Knobs the vector planner exposes via SQL.

All fields default to None / sensible defaults, in which case the executor falls back to the collection’s configured quantization and ef_search heuristic.

Parsed from an optional JSON-string third argument to vector_distance(field, query, '{"quantization":"rabitq","oversample":3}').

Fields

quantization: Option<VectorQuantization>

oversample: Option<u8>

query_dim: Option<u32>

meta_token_budget: Option<u8>

ef_search_override: Option<usize>

Override ef_search; falls back to 2 * top_k when None.

target_recall: Option<f32>

Target recall used with the cost model to escalate from coarse to fine quantization.

Implementations

impl VectorAnnOptions

pub fn to_runtime(&self) -> VectorAnnOptions

Convert into the runtime mirror used by nodedb-types.

Trait Implementations

impl Clone for VectorAnnOptions

fn clone(&self) -> VectorAnnOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorAnnOptions

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

Formats the value using the given formatter.

impl Default for VectorAnnOptions

fn default() -> VectorAnnOptions

Returns the “default value” for a type.

impl PartialEq for VectorAnnOptions

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