#[repr(C)]pub struct Rot2 { /* private fields */ }Expand description
Represents a rotation in the 2D plane.
A rotation of ๐/4 = 90ยฐ rotates the X axis to the Y axis.
Normally a Rot2 is normalized (unit-length).
If not, it will also scale vectors.

Sourcepub fn from_angle(angle: f32) -> Rot2
pub fn from_angle(angle: f32) -> Rot2
Angle is clockwise in radians. A ๐/4 = 90ยฐ rotation means rotating the X axis to the Y axis.
pub fn angle(self) -> f32
pub fn length_squared(self) -> f32
pub fn is_finite(self) -> bool
pub fn inverse(self) -> Rot2
