Implementations

impl SparseTensor

pub fn builder(shape: Vec<usize>, format: SparseFormat) -> SparseTensorBuilder

Create a sparse tensor builder.

pub fn format(&self) -> SparseFormat

Get the sparse format.

pub fn shape(&self) -> Vec<usize>

Get the shape.

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) -> Result<SparseTensor, SparseError>

Convert to CSR format.

pub fn to_csc(&self) -> Result<SparseTensor, SparseError>

Convert to CSC format.

pub fn to_coo(&self) -> Result<SparseTensor, SparseError>

Convert to COO format.

pub fn memory_bytes(&self) -> usize

Get memory usage in bytes.

Trait Implementations

impl Clone for SparseTensor

fn clone(&self) -> SparseTensor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseTensor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SparseTensor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SparseTensor

fn eq(&self, other: &SparseTensor) -> 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 SparseTensor

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
