Struct SparseVector

pub struct SparseVector { /* private fields */ }

A sparse vector.

Implementations

impl SparseVector

pub fn from_dense(vec: &[f32]) -> SparseVector

Creates a sparse vector from a dense vector.

pub fn from_map<'a, I: IntoIterator<Item = (&'a i32, &'a f32)>>( map: I, dim: i32, ) -> SparseVector

Creates a sparse vector from a map of non-zero elements.

pub fn dimensions(&self) -> i32

Returns the number of dimensions.

pub fn indices(&self) -> &[i32]

Returns the non-zero indices.

pub fn values(&self) -> &[f32]

Returns the non-zero values.

pub fn to_vec(&self) -> Vec<f32>

Returns the sparse vector as a Vec<f32>.

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.
