Trait for compressed column sparse matrix storage.

Required Methods

fn shape(&self) -> (R, C)

The shape of the stored matrix.

unsafe fn row_index_unchecked(&self, i: usize) -> usize

Retrieve the i-th row index of the underlying row index buffer.

Safety

No bound-checking is performed.

unsafe fn get_value_unchecked(&self, i: usize) -> &T

The i-th value on the contiguous value buffer of this storage.

Safety

No bound-checking is performed.

fn get_value(&self, i: usize) -> &T

The i-th value on the contiguous value buffer of this storage.

fn row_index(&self, i: usize) -> usize

Retrieve the i-th row index of the underlying row index buffer.

fn column_range(&self, i: usize) -> Range<usize>

The value indices for the i-th column.

fn len(&self) -> usize

The size of the value buffer (i.e. the entries known as possibly being non-zero).
