sourcepub fn cast_unit<Src2, Dst2>(&self) -> Rotation2D<T, Src2, Dst2>
pub fn cast_unit<Src2, Dst2>(&self) -> Rotation2D<T, Src2, Dst2>
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);
sourcepub fn to_untyped(&self) -> Rotation2D<T, UnknownUnit, UnknownUnit>
pub fn to_untyped(&self) -> Rotation2D<T, UnknownUnit, UnknownUnit>
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);
sourcepub fn from_untyped(r: &Rotation2D<T, UnknownUnit, UnknownUnit>) -> Self
pub fn from_untyped(r: &Rotation2D<T, UnknownUnit, UnknownUnit>) -> Self
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);
