#[repr(C)]
pub struct Translation2D<T, Src, Dst> { pub x: T, pub y: T, /* private fields */ }
Expand description

A 2d transformation from a space to another that can only express translations.

The main benefit of this type over a Vector2D is the ability to cast between source and destination spaces.

Example:

use euclid::{Translation2D, Point2D, point2};
struct ParentSpace;
struct ChildSpace;
type ScrollOffset = Translation2D<i32, ParentSpace, ChildSpace>;
type ParentPoint = Point2D<i32, ParentSpace>;
type ChildPoint = Point2D<i32, ChildSpace>;

let scrolling = ScrollOffset::new(0, 100);
let p1: ParentPoint = point2(0, 0);
let p2: ChildPoint = scrolling.transform_point(p1);
