Struct nalgebra_sparse::csr::CsrRowMut

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

A mutable representation of a row in a CSR matrix.

Note that only explicitly stored entries can be mutated. The sparsity pattern belonging to the row cannot be modified.

Implementations

impl<'a, T> CsrRowMut<'a, T>

pub fn ncols(&self) -> usize

The number of global columns in the row.

pub fn nnz(&self) -> usize

The number of non-zeros in this row.

pub fn col_indices(&self) -> &[usize]

The column indices corresponding to explicitly stored entries in this row.

pub fn values(&self) -> &[T]

The values corresponding to explicitly stored entries in this row.

pub fn get_entry(&self, global_col_index: usize) -> Option<SparseEntry<'_, T>>

Returns an entry for the given global column index.

Each call to this function incurs the cost of a binary search among the explicitly stored column entries.

impl<'a, T> CsrRowMut<'a, T>

pub fn values_mut(&mut self) -> &mut [T]

Mutable access to the values corresponding to explicitly stored entries in this row.

pub fn cols_and_values_mut(&mut self) -> (&[usize], &mut [T])

Provides simultaneous access to column indices and mutable values corresponding to the explicitly stored entries in this row.

This method primarily facilitates low-level access for methods that process data stored in CSR format directly.

pub fn get_entry_mut(
    &mut self,
    global_col_index: usize
) -> Option<SparseEntryMut<'_, T>>

Returns a mutable entry for the given global column index.

Trait Implementations

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

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

Formats the value using the given formatter.

impl<'a, T: PartialEq> PartialEq<CsrRowMut<'a, T>> for CsrRowMut<'a, T>

fn eq(&self, other: &CsrRowMut<'a, T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
