Struct Vec2D 

pub struct Vec2D<T> { /* private fields */ }

A row-major contiguous two-dimensional array.

Implementations

impl<T> Vec2D<T>

pub fn new() -> Self

Construct a new empty Vec2D

pub fn from_vec(data: Vec<T>, n_columns: usize) -> Self

Take ownership of a Vec<T> and reinterpret as two-dimensional data.

Panics if data.len() is not an integer multiple of n_columns.

pub fn n_cols(&self) -> usize

Return number of columns

pub fn n_rows(&self) -> usize

Return number of rows

pub fn iter<'a>(&'a self) -> Chunks<'a, T>

Iterate over rows

impl<T: Clone> Vec2D<T>

pub fn from_slice(x: &[T], n_columns: usize) -> Vec2D<T>

Copy data from a slice and reinterpret as two-dimensional.

Panics if x.len() is not an integer multiple of n_columns.
