Struct Dimensions 

pub struct Dimensions {
    pub rows: usize,
    pub columns: usize,
}

Non-zero rectangle dimensions

let d = Dimensions::from ((3, 2));
assert_eq!(d.rows, 3);
assert_eq!(d.columns,  2);
assert_eq!(d.area(), 6);
assert!( d.contains ((1, 1).into()));
assert!(!d.contains ((4, 1).into()));
assert!(!d.contains ((1, 3).into()));
let rect = Rectangle::from (d);
assert_eq!(rect.min(), (0, 0).into());
assert_eq!(rect.max(), (2, 1).into());

Implementations

impl Dimensions

pub const fn area(&self) -> usize

Trait Implementations

impl Add<Dimensions> for Coordinate

type Output = Coordinate

The resulting type after applying the + operator.

fn add(self, rhs: Dimensions) -> Coordinate

Performs the + operation.

impl Add for Dimensions

type Output = Dimensions

The resulting type after applying the + operator.

fn add(self, rhs: Dimensions) -> Dimensions

Performs the + operation.

impl Clone for Dimensions

fn clone(&self) -> Dimensions

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Dimensions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Dimensions

fn default() -> Dimensions

Returns the “default value” for a type.

impl From<[usize; 2]> for Dimensions

fn from([rows, columns]: [usize; 2]) -> Self

Converts to this type from the input type.

impl From<(usize, usize)> for Dimensions

fn from((rows, columns): (usize, usize)) -> Self

Converts to this type from the input type.

impl From<Dimensions> for [usize; 2]

fn from(_: Dimensions) -> Self

Converts to this type from the input type.

impl From<Dimensions> for (usize, usize)

fn from(_: Dimensions) -> Self

Converts to this type from the input type.

impl From<Dimensions> for Rectangle

fn from(dimensions: Dimensions) -> Self

Converts to this type from the input type.

impl PartialEq for Dimensions

fn eq(&self, other: &Dimensions) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub<Dimensions> for Coordinate

type Output = Coordinate

The resulting type after applying the - operator.

fn sub(self, rhs: Dimensions) -> Coordinate

Performs the - operation.

impl Sub for Dimensions

type Output = Dimensions

The resulting type after applying the - operator.

fn sub(self, rhs: Dimensions) -> Dimensions

Performs the - operation.

impl Copy for Dimensions

impl Eq for Dimensions

impl StructuralPartialEq for Dimensions
