Trait for quarternions.

Required Associated Types

type S: Scalar

The scalar type of the coordinates and angles used in the rotation.

type Vec3: Vector3D<S = Self::S>

The 3d vector type used in the rotation.

type Vec4: Vector4D<S = Self::S>

The 4d vector type used in the rotation.

Required Methods

fn identity() -> Self

Returns the identity rotation.

fn from_rotation_arc(from: Self::Vec3, to: Self::Vec3) -> Self

Returns a rotation from a rotation arc.

fn from_axis_angle(axis: Self::Vec3, angle: Self::S) -> Self

Returns a rotation from an axis and an angle.

fn axis_angle(&self) -> (Self::Vec3, Self::S)

Returns the axis and angle of the rotation.

fn vec4(&self) -> Self::Vec4

Returns the matrix representation of the rotation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
