Struct SparseVector 

pub struct SparseVector {
    pub entries: Vec<(u32, f32)>,
}

A sparse vector represented as (index, value) pairs.

Fields

entries: Vec<(u32, f32)>

Non-zero entries as (index, value) pairs

Implementations

impl SparseVector

pub fn new(entries: Vec<(u32, f32)>) -> Self

Creates a new sparse vector from entries

pub fn len(&self) -> usize

Returns the number of non-zero entries

pub fn is_empty(&self) -> bool

Returns true if there are no entries

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

Computes the dot product with another sparse vector

Trait Implementations

impl Clone for SparseVector

fn clone(&self) -> SparseVector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseVector

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

Formats the value using the given formatter.

impl PartialEq for SparseVector

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