Struct alg_ds::ds::matrix::Matrix

pub struct Matrix<'a, T> where
    T: Default + Clone,  { /* fields omitted */ }

Rectangular table of elements (two-dimensional array).

Methods

impl<'a, T> Matrix<'a, T> where
    T: Default + Clone, 

pub fn new(rows: usize, cols: usize) -> Self

Creates new Matrix and fills it with default values.

rows - rows number. cols - columns number. Panic, if memory allocation is not succesfully.

pub fn clear(&mut self)

Fills matrix with a default values.

pub fn fill(&mut self, value: T)

Fills matrix with a value.

pub fn rows(&self) -> usize

Returns rows number.

pub fn cols(&self) -> usize

Returns columns number.

pub fn elements_number(&self) -> usize

Returns number of elements in matrix.

pub fn nth(&self, index: usize) -> &T

Returns the n-th element of the table in line traversal order.

pub fn get(&self, row: usize, col: usize) -> &T

Returns value at [row][col] position.

There are bounds checking. If index out of range, then panic.

pub fn set(&mut self, row: usize, col: usize, value: T)

Sets the value of element at [row][col] position.

There are bounds checking. If index out of range, then panic.

pub fn iter(&self) -> Iter<T>

Iterator over matrix in line traversal order.

pub fn iter_mut(&mut self) -> IterMut<T>

Mutable iterator over matrix in line traversal order.

Trait Implementations
