pub trait KNearestSearch: Default {
    fn build(&mut self, data: Matrix<f64>);
    fn search(
        &self,
        point: &[f64],
        k: usize
    ) -> Result<(Vec<usize>, Vec<f64>), Error>;
}

Search K-nearest items

Required Methods

fn build(&mut self, data: Matrix<f64>)

build data structure for search optimization

fn search(&self, point: &[f64], k: usize) -> Result<(Vec<usize>, Vec<f64>), Error>

Serch k-nearest items close to the point Returns a tuple of searched item index and its distances
