}
Expand description

2D size.

Size is used to define the width and height of an object.

Nalgebra support can be enabled with the nalgebra_support feature. This implements From<Vector2<N>> and From<&Vector2<N>> where N is Scalar + Into<u32>. This allows use of Nalgebra’s Vector2 with embedded-graphics where u32, u16 or u8 is used for value storage.

§Examples

§Create a Size from two integers

use embedded_graphics::geometry::Size;

// Create a size using the `new` constructor method
let s = Size::new(10, 20);

§Create a Size from a Nalgebra Vector2

Be sure to enable the nalgebra_support feature to get Nalgebra integration.

Any Vector2<N> can be used where N: Into<u32> + nalgebra::Scalar. This includes the primitive types u32, u16 and u8.

use embedded_graphics::geometry::Size;
use nalgebra::Vector2;

assert_eq!(Size::from(Vector2::new(10u32, 20)), Size::new(10u32, 20));
assert_eq!(Size::from(Vector2::new(10u16, 20)), Size::new(10u32, 20));
assert_eq!(Size::from(Vector2::new(10u8, 20)), Size::new(10u32, 20));

.into() can also be used, but may require more type annotations:

use embedded_graphics::geometry::Size;
use nalgebra::Vector2;

let c: Size = Vector2::new(10u32, 20).into();

assert_eq!(c, Size::new(10u32, 20));

Fields§
