Struct extendr_api::prelude::utils::constrained::sparse::SymbolicSparseColMatRef

pub struct SymbolicSparseColMatRef<'nrows, 'ncols, 'a, I>(/* private fields */)
where
    I: Index;

Symbolic structure view with dimensions equal to the values tied to ('nrows, 'ncols), in column-major order.

Implementations

impl<'nrows, 'ncols, 'a, I> SymbolicSparseColMatRef<'nrows, 'ncols, 'a, I>

where I: Index,

pub fn new( inner: SymbolicSparseColMatRef<'a, I>, nrows: Size<'nrows>, ncols: Size<'ncols>, ) -> SymbolicSparseColMatRef<'nrows, 'ncols, 'a, I>

Returns a new symbolic structure after checking that its dimensions match the dimensions tied to ('nrows, 'ncols).

pub fn into_inner(self) -> SymbolicSparseColMatRef<'a, I>

Returns the unconstrained symbolic structure.

pub fn nrows(&self) -> Size<'nrows>

Returns the number of rows of the matrix.

pub fn ncols(&self) -> Size<'ncols>

Returns the number of columns of the matrix.

pub fn row_indices_of_col_raw( &self, j: Idx<'ncols, usize>, ) -> &'a [Idx<'nrows, I>]

Returns the row indices in column j.

pub fn row_indices_of_col( &self, j: Idx<'ncols, usize>, ) -> impl ExactSizeIterator + DoubleEndedIterator + 'a

Returns the row indices in column j.
