Struct SparseVec 

pub struct SparseVec<T> { /* private fields */ }

A sparse vector storing only non-zero/non-default entries.

Implementations

impl<T: Clone + PartialEq> SparseVec<T>

pub fn new(length: usize, default_val: T) -> Self

Create a sparse vec with given length and default value.

pub fn set(&mut self, i: usize, value: T)

Set position i to value.

pub fn get(&self, i: usize) -> &T

Get the value at position i.

pub fn len(&self) -> usize

Return the logical length.

pub fn is_empty(&self) -> bool

Return true if logical length is zero.

pub fn nnz(&self) -> usize

Return the number of non-default entries.
