Trait CsrMatrixViewMethods 

pub trait CsrMatrixViewMethods<'a, T> {
    // Required methods
    fn nrows(self) -> usize;
    fn ncols(self) -> usize;
    fn get_row(self, row_index: usize) -> CsVecRef<'a, T>;

    // Provided method
    fn to_dense(self) -> DMatrix<T>
       where Self: Sized + Copy,
             T: Real { ... }
}

Trait providing methods for CSR matrix view operations.

This trait extends types that can be converted to CSR views with convenient methods for matrix operations and introspection.

Required Methods

fn nrows(self) -> usize

Returns the number of rows in the matrix.

fn ncols(self) -> usize

Returns the number of columns in the matrix.

fn get_row(self, row_index: usize) -> CsVecRef<'a, T>

Gets a row as a sparse vector.

Arguments

• row_index - Index of the row to retrieve

Returns

A CsVecRef representing the sparse vector for this row

Provided Methods

fn to_dense(self) -> DMatrix<T>

where Self: Sized + Copy, T: Real,

Converts to a dense matrix.

This allocates a new dense matrix and copies all non-zero elements.

Returns

A dense DMatrix containing the same data

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
