Struct CsMatrixView 

pub struct CsMatrixView<'a, T> { /* private fields */ }

An immutable view of a compressed sparse matrix.

This provides efficient read-only access to sparse matrix data without allocation. Views can be created from both mutable and immutable matrices and are useful for passing matrices to functions without transferring ownership.

The view has the same format capabilities as CsMatrix - it can represent both CSR and CSC formats depending on how it’s created.

Implementations

impl<'a, T> CsMatrixView<'a, T>

where T: RealField,

pub fn num_primary(&self) -> usize

Returns the number of primary axes (rows for CSR, columns for CSC).

pub fn num_secondary(&self) -> usize

Returns the number of secondary axes (columns for CSR, rows for CSC).

pub fn get_lane(self, lane_index: usize) -> CsVecRef<'a, T>

Gets a lane (row for CSR, column for CSC) as an immutable sparse vector.

Arguments

• lane_index - Index of the lane to retrieve

Returns

A CsVecRef representing the sparse vector for this lane

pub fn dense_rate(&self) -> f32

Returns the density rate of the matrix.

This is the ratio of non-zero elements to total elements. A value of 0.1 means 10% of elements are non-zero.

Trait Implementations

impl<'a, T: Clone> Clone for CsMatrixView<'a, T>

fn clone(&self) -> CsMatrixView<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug> Debug for CsMatrixView<'a, T>

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

Formats the value using the given formatter.

impl<'a, T> IntoView for CsMatrixView<'a, T>

type View = CsMatrixView<'a, T>

The view type produced by this trait.

fn into_view(self) -> Self::View

Converts the type into an immutable view.
