Struct euclid::TypedTranslation2D

#[repr(C)]
pub struct TypedTranslation2D<T, Src, Dst> {
    pub x: T,
    pub y: T,
    // some fields omitted
}

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

The main benefit of this type over a TypedVector2D is the ability to cast between a source and a destination spaces.

Example:

use euclid::{TypedTranslation2D, TypedPoint2D, point2};
struct ParentSpace;
struct ChildSpace;
type ScrollOffset = TypedTranslation2D<i32, ParentSpace, ChildSpace>;
type ParentPoint = TypedPoint2D<i32, ParentSpace>;
type ChildPoint = TypedPoint2D<i32, ChildSpace>;

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