Struct shine_graph::smat::HCSMatrixMask

pub struct HCSMatrixMask { /* fields omitted */ }

Compressed Sparse (Square) Row matrix. Its a variant of the CSR data structure where a HashMap is used to store the data ranges for the occupied rows.

Methods

impl HCSMatrixMask

pub fn new_with_capacity(nnz_capacity: usize) -> HCSMatrixMask

Creates a new HCSMatrixMask with the given

pub fn new() -> HCSMatrixMask

Creates an empty HCSMatrixMask

Trait Implementations

impl MatrixMask for HCSMatrixMask

fn clear(&mut self)

Remove all the items.

fn add(&mut self, _major: usize, _minor: usize) -> (DataPosition, bool)

Store an item and return a tuple where - the first item is its position in the flattened array - the second item is true if it was an unoccupied item, false otherwise.

fn remove(
    &mut self,
    _major: usize,
    _minor: usize
) -> Option<(DataPosition, DataRange)>

Remove an item and return its position in the flattened array and the new range for the this row

fn get_data_range(&self, _major: usize) -> DataRange

Return the range of position for the given row in the flattened array.

fn lower_bound_column_position(
    &self,
    _column: usize,
    _range: DataRange
) -> Option<(usize, DataPosition)>

Find the first valid column index and its position that is not less than the provided index.

fn get_column_index(&self, _pos: DataPosition) -> usize

Gets the column index of item stored at the given position in the flattend array.

impl Default for HCSMatrixMask

fn default() -> Self

Returns the "default value" for a type.
