Struct CscColMut 

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

A mutable representation of a column in a CSC matrix.

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

Implementations

impl<'a, T> CscColMut<'a, T>

pub fn nrows(&self) -> usize

The number of global rows in the column.

pub fn nnz(&self) -> usize

The number of non-zeros in this column.

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

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

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

The values corresponding to explicitly stored entries in this column.

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

Returns an entry for the given global row index.

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

impl<'a, T> CscColMut<'a, T>

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

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

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

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

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

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

Returns a mutable entry for the given global row index.

Trait Implementations

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

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

Formats the value using the given formatter.

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

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

Tests for self and other values to be equal, and is used by ==.

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

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