Implementations

impl VectorDistance

pub fn from_function_name(name: &str) -> Option<Self>

pub const fn function_name(self) -> &'static str

pub fn distance(self, left: VectorRef<'_>, right: VectorRef<'_>) -> Result<f64>

pub fn distance_with_work( self, left: VectorRef<'_>, right: VectorRef<'_>, checkpoint: impl FnMut() -> Result<()>, ) -> Result<f64>

Cooperatively scores canonical values without copying their payloads.

pub fn distance_slices_with_work( self, left: &[f32], right: &[f32], checkpoint: impl FnMut() -> Result<()>, ) -> Result<f64>

Scores admitted raw projection vectors with the same mathematical contract as SQL/Cypher, without creating canonical payload copies.

pub fn evaluate( self, left: ValueRef<'_>, right: ValueRef<'_>, ) -> Result<Option<f64>>
