Implementations

impl SparseCOO

pub fn new(rows: usize, cols: usize) -> Self

Create a new empty COO matrix.

pub fn add_entry( &mut self, row: usize, col: usize, value: f64, ) -> Result<(), SparseError>

Add a non-zero entry.

pub fn nnz(&self) -> usize

Get the number of non-zero elements.

pub fn sparsity_ratio(&self) -> f64

Get sparsity ratio.

pub fn to_csr(&self) -> SparseCSR

Convert to CSR format.

pub fn to_csc(&self) -> SparseCSC

Convert to CSC format.

Trait Implementations

impl Clone for SparseCOO

fn clone(&self) -> SparseCOO

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseCOO

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SparseCOO

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparseCOO

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

impl Serialize for SparseCOO

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
