Struct SparseVector 

pub struct SparseVector {
    pub ids: Vec<u32>,
    pub weights: Vec<f32>,
}

A sparse vector: term ids ascending with their weights.

Fields

ids: Vec<u32>

weights: Vec<f32>

Implementations

impl SparseVector

pub fn from_pairs(pairs: impl IntoIterator<Item = (u32, f32)>) -> Self

Builds a vector from (id, weight) pairs, sorting them by id and dropping zeros and negative weights; duplicate ids are summed.

pub fn dot(&self, other: &SparseVector) -> f32

Exact dot product with another vector (both ascending).
