Struct vec2dim::Vec2d

pub struct Vec2d<T> { /* fields omitted */ }

A two-dimensional array. Unlike a standard vector, Vec2d must maintain a constant number of elements equal to its number of rows times its number of columns.

Methods

impl<T: Default> Vec2d<T>

pub fn new_with_default(rows: usize, cols: usize) -> Vec2d<T>

Creates a new Vec2d<T> and initializes all the values to T::default().

pub fn add_row_of_default(&mut self)

Adds a new row to the vector and sets all elements of that row to T::default().

impl<T: Copy> Vec2d<T>

pub fn new_with_value(rows: usize, cols: usize, val: T) -> Vec2d<T>

Creates a new Vec2d<T> and initializes all the values to a copy of val.

impl<T> Vec2d<T>

pub fn new() -> Vec2d<T>

Creates a new Vec2d<T> with no rows, columns, or elements.

pub fn count(&self) -> usize

Returns the number of elements in the array. Equal to the number of rows times the number of columns.

pub fn count_cols(&self) -> usize

Returns the number of columns of the array.

pub fn count_rows(&self) -> usize

Returns the number of rows of the array.

pub fn size(&self) -> (usize, usize)

Returns the dimensions of the array as a tuple of (row, col).

Trait Implementations

impl<T> Index<usize> for Vec2d<T>

type Output = [T]

The returned type after indexing.

fn index(&self, row: usize) -> &[T]

Performs the indexing (container[index]) operation.

impl<T> IndexMut<usize> for Vec2d<T>

fn index_mut<'a>(&'a mut self, row: usize) -> &'a mut Self::Output

Performs the mutable indexing (container[index]) operation.
