Struct rulinalg::matrix::MatrixSliceMut

pub struct MatrixSliceMut<'a, T: 'a> {
    // some fields omitted
}

A mutable MatrixSliceMut

This struct provides a mutable slice into a matrix.

The struct contains the upper left point of the slice and the width and height of the slice.

Methods

impl<'a, T> MatrixSliceMut<'a, T>

fn iter_rows(&self) -> Rows<T>

Iterate over the rows of the mutable matrix slice.

Examples

use rulinalg::matrix::{Matrix, MatrixSliceMut};

let mut a = Matrix::new(3 ,2, (0..6).collect::<Vec<usize>>());
let b = MatrixSliceMut::from_matrix(&mut a, [0,0], 2, 2);

// Prints "2" two times.
for row in b.iter_rows() {
    println!("{}", row.len());
}

fn iter_rows_mut(&self) -> RowsMut<T>

Iterate over the mutable rows of the matrix.

Examples

use rulinalg::matrix::{Matrix, MatrixSliceMut};

let mut a = Matrix::new(3, 2, (0..6).collect::<Vec<usize>>());

// New scope (so we can consume `a` after)
{
   let b = MatrixSliceMut::from_matrix(&mut a, [0,0], 2, 2);

    for row in b.iter_rows_mut() {
        for r in row {
            *r = *r + 1;
        }
    }
}

// The first two rows have been incremented by 1
println!("{}", a);

impl<'a, T> MatrixSliceMut<'a, T>

fn from_matrix(mat: &'a mut Matrix<T>, start: [usize; 2], rows: usize, cols: usize) -> MatrixSliceMut<T>

Produce a matrix slice from a matrix

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());
let slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);

unsafe fn from_raw_parts(ptr: *mut T, rows: usize, cols: usize, row_stride: usize) -> MatrixSliceMut<'a, T>

Creates a mutable matrix slice from raw parts.

Examples

use rulinalg::matrix::MatrixSliceMut;

let mut a = vec![4.0; 16];

unsafe {
    // Create a mutable matrix slice with 3 rows, and 3 cols
    // The row stride of 4 specifies the distance between the start of each row in the data.
    let b = MatrixSliceMut::from_raw_parts(a.as_mut_ptr(), 3, 3, 4);
}

Safety

The pointer must be followed by a contiguous slice of data larger than row_stride * rows. If not then other operations will produce undefined behaviour.

Additionally cols should be less than the row_stride. It is possible to use this function safely whilst violating this condition. So long as max(cols, row_stride) * rows is less than the data size.

fn reslice(self, start: [usize; 2], rows: usize, cols: usize) -> MatrixSliceMut<'a, T>

Produce a matrix slice from an existing matrix slice.

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());
let slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);
let new_slice = slice.reslice([0,0], 1, 1);

fn iter(&self) -> SliceIter<'a, T>

Returns an iterator over the matrix slice.

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());
let slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);

let slice_data = slice.iter().map(|v| *v).collect::<Vec<usize>>();
assert_eq!(slice_data, vec![4,5,7,8]);

fn iter_mut(&mut self) -> SliceIterMut<'a, T>

Returns a mutable iterator over the matrix slice.

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());

{
    let mut slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);

    for d in slice.iter_mut() {
        *d = *d + 2;
    }
}

// Only the matrix slice is updated.
assert_eq!(a.into_vec(), vec![0,1,2,3,6,7,6,9,10]);

fn get_row_mut(&mut self, index: usize) -> Option<&mut [T]>

Returns a mutable reference to the row of a MatrixSliceMut at the given index. None if the index is out of bounds.

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());
let mut slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);
{
    let row = slice.get_row_mut(1);
    let mut expected = vec![7usize, 8];
    assert_eq!(row, Some(&mut *expected));
}
assert!(slice.get_row_mut(5).is_none());

unsafe fn get_row_unchecked_mut(&mut self, index: usize) -> &mut [T]

Returns a mutable reference to the row of a MatrixSliceMut at the given index without doing unbounds checking

Examples

use rulinalg::matrix::Matrix;
use rulinalg::matrix::MatrixSliceMut;

let mut a = Matrix::new(3,3, (0..9).collect::<Vec<usize>>());
let mut slice = MatrixSliceMut::from_matrix(&mut a, [1,1], 2, 2);
let row = unsafe { slice.get_row_unchecked_mut(1) };
let mut expected = vec![7usize, 8];
assert_eq!(row, &mut *expected);

impl<'a, T: Copy> MatrixSliceMut<'a, T>

fn into_matrix(self) -> Matrix<T>

Convert the matrix slice into a new Matrix.

fn set_to(self, target: MatrixSlice<T>)

Sets the underlying matrix data to the target data.

Examples

use rulinalg::matrix::{Matrix, MatrixSliceMut};

let mut mat = Matrix::<f32>::zeros(4,4);
let one_block = Matrix::<f32>::ones(2,2);

// Get a mutable slice of the upper left 2x2 block.
let mat_block = MatrixSliceMut::from_matrix(&mut mat, [0,0], 2, 2);

// Set the upper left 2x2 block to be ones.
mat_block.set_to(one_block.as_slice());

Panics

Panics if the dimensions of self and target are not the same.
