Struct VectorDistanceExpr 

pub struct VectorDistanceExpr { /* private fields */ }

Builder returned by FieldRef::distance_to — chain a comparator (.lt/.lte/.gt/.gte/.eq) for a threshold filter, or .asc/ .desc to use it as an ORDER BY target. The common k-NN “closest first” case is .asc(); see also FieldRef::order_by_distance, sugar for exactly that.

Implementations

impl VectorDistanceExpr

pub fn lt<V: IntoSqlValue>(self, value: V) -> FilterExpr

pub fn lte<V: IntoSqlValue>(self, value: V) -> FilterExpr

pub fn gt<V: IntoSqlValue>(self, value: V) -> FilterExpr

pub fn gte<V: IntoSqlValue>(self, value: V) -> FilterExpr

pub fn eq<V: IntoSqlValue>(self, value: V) -> FilterExpr

pub fn asc(self) -> OrderClause

Order by distance, nearest first (ASC) — the standard k-NN shape. Equivalent to FieldRef::order_by_distance.

pub fn desc(self) -> OrderClause

Order by distance, farthest first (DESC) — e.g. diverse / furthest-point sampling.
