A transform that can represent rotations in 2d, represented as an angle in radians.
Fields
angle: T
Angle in radians
Implementations
impl<T, Src, Dst> Rotation2D<T, Src, Dst>
[src]
pub fn new(angle: Angle<T>) -> Self
[src]
Creates a rotation from an angle in radians.
pub fn radians(angle: T) -> Self
[src]
Creates a rotation from an angle in radians.
pub fn identity() -> Self where
T: Zero,
[src]
T: Zero,
Creates the identity rotation.
impl<T: Copy, Src, Dst> Rotation2D<T, Src, Dst>
[src]
pub fn cast_unit<Src2, Dst2>(&self) -> Rotation2D<T, Src2, Dst2>
[src]
Cast the unit, preserving the numeric value.
Example
enum Local {} enum World {} enum Local2 {} enum World2 {} let to_world: Rotation2D<_, Local, World> = Rotation2D::radians(42); assert_eq!(to_world.angle, to_world.cast_unit::<Local2, World2>().angle);
pub fn to_untyped(&self) -> Rotation2D<T, UnknownUnit, UnknownUnit>
[src]
Drop the units, preserving only the numeric value.
Example
enum Local {} enum World {} let to_world: Rotation2D<_, Local, World> = Rotation2D::radians(42); assert_eq!(to_world.angle, to_world.to_untyped().angle);
pub fn from_untyped(r: &Rotation2D<T, UnknownUnit, UnknownUnit>) -> Self
[src]
Tag a unitless value with units.
Example
use euclid::UnknownUnit; enum Local {} enum World {} let rot: Rotation2D<_, UnknownUnit, UnknownUnit> = Rotation2D::radians(42); assert_eq!(rot.angle, Rotation2D::<_, Local, World>::from_untyped(&rot).angle);

[src]
pub fn to_3d(&self) -> Rotation3D<T, Src, Dst>
[src]
Creates a 3d rotation (around the z axis) from this 2d rotation.
pub fn inverse(&self) -> Rotation2D<T, Dst, Src>
[src]
Returns the inverse of this rotation.
pub fn pre_rotate<NewSrc>(
&self,
other: &Rotation2D<T, NewSrc, Src>
) -> Rotation2D<T, NewSrc, Dst>
[src]
&self,
other: &Rotation2D<T, NewSrc, Src>
) -> Rotation2D<T, NewSrc, Dst>

other: &Rotation2D<T, Dst, NewDst>
) -> Rotation2D<T, Src, NewDst>
[src]
&self,
other: &Rotation2D<T, Dst, NewDst>
) -> Rotation2D<T, Src, NewDst>
Returns a rotation representing this rotation followed by the other rotation.
pub fn transform_point(&self, point: Point2D<T, Src>) -> Point2D<T, Dst>
[src]
Returns the given 2d point transformed by this rotation.
The input point must be use the unit Src, and the returned point has the unit Dst.
pub fn transform_vector(&self, vector: Vector2D<T, Src>) -> Vector2D<T, Dst>
[src]
Returns the given 2d vector transformed by this rotation.
The input point must be use the unit Src, and the returned point has the unit Dst.
