[−][src]Struct vec2dim::Vec2d
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>
[src]
pub fn new_with_default(rows: usize, cols: usize) -> Vec2d<T>
[src]
Creates a new Vec2d<T>
and initializes all the values to T::default()
.
pub fn add_row_of_default(&mut self)
[src]
Adds a new row to the vector and sets all elements of that row to T::default()
.
If the array is empty, creates a row of one element.
pub fn add_col_of_default(&mut self)
[src]
Adds a new column to the array and sets all elements of the column to T::default()
.
impl<T: Copy> Vec2d<T>
[src]
pub fn new_with_value(rows: usize, cols: usize, val: T) -> Vec2d<T>
[src]
Creates a new Vec2d<T>
and initializes all the values to a copy of val
.
pub fn from(width: usize, arr: &[T]) -> Vec2d<T>
[src]
Creates a new Vec2d<T>
from an array slice.
The slice must have a length that is divisible by cols
in order to fill the new array.
The array is filled left to right, top to bottom.
pub fn insert_col(&mut self, index: usize, data: &[T])
[src]
Inserts a column of data before the columns indicated by index
.
pub fn insert_row(&mut self, index: usize, data: &[T])
[src]
Inserts a row of data before the row indicated by index
. If index
is 0
, calls
push_row(data)
.
pub fn push_col(&mut self, data: &[T])
[src]
Adds a new column of data to the right edge of the array. The length of the slice data
must be exactly equal to the height of the array.
pub fn push_row(&mut self, data: &[T])
[src]
Adds a row of data at the bottom of the array. The length of the slice data
must be
exactly equal to the array width or the method will panic.
impl<T: PartialEq> Vec2d<T>
[src]
pub fn contains(&self, val: &T) -> bool
[src]
Checks if val
is equivalent to any of the elements in the array.
Returns true
if there is a match, false
otherwise.
impl<T> Vec2d<T>
[src]
pub fn new() -> Vec2d<T>
[src]
Creates a new Vec2d<T>
with no rows, columns, or elements.
pub fn from_fn(
rows: usize,
cols: usize,
initializer: &dyn Fn(usize, usize) -> T
) -> Vec2d<T>
[src]
rows: usize,
cols: usize,
initializer: &dyn Fn(usize, usize) -> T
) -> Vec2d<T>
Creates a new Vec2d<T>
and initializes its values from initializer
,
a passed-in function that takes the current cell index (row and column)
and returns a T
.
pub fn as_ptr(&self) -> *const T
[src]
Returns a raw pointer to the underlying vector's buffer.
pub fn as_vec(&self) -> &Vec<T>
[src]
Returns a reference to the underlying vector.
pub fn count(&self) -> usize
[src]
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
[src]
Returns the number of columns of the array.
pub fn count_rows(&self) -> usize
[src]
Returns the number of rows of the array.
pub fn size(&self) -> (usize, usize)
[src]
Returns the dimensions of the array as a tuple of (row, col).
