Enum SparseFormat 

pub enum SparseFormat {
    COO,
    CSR,
    CSC,
    BSR,
    DIA,
    ELL,
}

Sparse tensor storage formats

Variants

COO

Coordinate format: stores (indices, values) pairs Memory: O(nnz) for indices + values Good for: construction, element access

CSR

Compressed Sparse Row format Memory: O(nnz) values + O(nnz) column indices + O(rows+1) row pointers Good for: matrix-vector multiplication, row access

CSC

Compressed Sparse Column format Memory: O(nnz) values + O(nnz) row indices + O(cols+1) column pointers Good for: matrix-vector multiplication (transposed), column access

BSR

Block Sparse Row format for structured sparsity Good for: GPU acceleration, structured pruning

DIA

Diagonal format for diagonal and band matrices Good for: diagonal matrices, finite difference operators

ELL

ELLPack format for GPU-optimized sparse operations Good for: GPU kernels with regular sparsity patterns

Implementations

impl SparseFormat

pub fn name(self) -> &'static str

Get human-readable name

pub fn supports_row_access(self) -> bool

Check if format supports efficient row access

pub fn supports_column_access(self) -> bool

Check if format supports efficient column access

pub fn is_gpu_friendly(self) -> bool

Check if format is suitable for GPU operations

Trait Implementations

impl Clone for SparseFormat

fn clone(&self) -> SparseFormat

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SparseFormat

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

Formats the value using the given formatter.

impl Display for SparseFormat

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

Formats the value using the given formatter.

impl Hash for SparseFormat

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SparseFormat

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