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);

is zero()
).
sourcepub fn is_identity(&self) -> bool
pub fn is_identity(&self) -> bool

).

sourcepub fn transform_size(&self, s: Size2D<T, Src>) -> Size2D<T, Dst>
pub fn transform_size(&self, s: Size2D<T, Src>) -> Size2D<T, Dst>
No-op, just cast the unit.

sourcepub fn to_untyped(&self) -> Translation2D<T, UnknownUnit, UnknownUnit>
pub fn to_untyped(&self) -> Translation2D<T, UnknownUnit, UnknownUnit>
Drop the units, preserving only the numeric value.

) -> Translation2D<T, Src, Dst>
pub fn from_untyped( t: &Translation2D<T, UnknownUnit, UnknownUnit>, ) -> Translation2D<T, Src, Dst>
Tag a unitless value with units.
sourcepub fn to_transform(&self) -> Transform2D<T, Src, Dst>
pub fn to_transform(&self) -> Transform2D<T, Src, Dst>
Returns the matrix representation of this translation.

NewT: NumCast,
pub fn cast<NewT>(self) -> Translation2D<NewT, Src, Dst>where
NewT: NumCast,
Cast from one numeric representation to another, preserving the units.
When casting from floating vector to integer coordinates, the decimals are truncated
as one would expect from a simple cast, but this behavior does not always make sense
geometrically. Consider using round()
, ceil()
or floor()
before casting.
sourcepub fn try_cast<NewT>(self) -> Option<Translation2D<NewT, Src, Dst>>where
NewT: NumCast,
pub fn try_cast<NewT>(self) -> Option<Translation2D<NewT, Src, Dst>>where
NewT: NumCast,
Fallible cast from one numeric representation to another, preserving the units.

as one would expect from a simple cast, but this behavior does not always make sense

pub fn to_usize(self) -> Translation2D<usize, Src, Dst>

vector, truncating decimals if any.
When casting from floating vector vectors, it is worth considering whether
to round()
, ceil()
or floor()
before the cast in order to obtain
the desired conversion behavior.
sourcepub fn to_u32(self) -> Translation2D<u32, Src, Dst>
pub fn to_u32(self) -> Translation2D<u32, Src, Dst>
Cast into an u32
