Enum SparseFormat 

#[non_exhaustive]
pub enum SparseFormat {
    Coo,
    Csr,
    Csc,
}

Sparse matrix storage format

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Coo

Coordinate format (COO)

Stores explicit (row, col, value) triplets. Best for: construction, format conversion, random access insertion Storage: O(3 * nnz)

Csr

Compressed Sparse Row (CSR)

Row pointers + column indices + values. Best for: row slicing, SpMV, most sparse operations Storage: O(2 * nnz + nrows + 1)

Csc

Compressed Sparse Column (CSC)

Column pointers + row indices + values. Best for: column slicing, transposed operations Storage: O(2 * nnz + ncols + 1)

Implementations

impl SparseFormat

pub fn is_row_major(&self) -> bool

Returns true if format is efficient for row operations

pub fn is_col_major(&self) -> bool

Returns true if format is efficient for column operations

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

Returns the format name as a string

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.
