Struct euclid::Translation2D [−][src]
#[repr(C)]pub struct Translation2D<T, Src, Dst> { pub x: T, pub y: T, // some fields omitted }
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 a source and a 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);
Fields
x: T
y: T
