Struct jumpy::prelude::egui::epaint::emath::Rot2

#[repr(C)]
pub struct Rot2 {
    s: f32,
    c: f32,
}
Expand description

Represents a rotation in the 2D plane. A rotation of ๐žƒ/4 = 90ยฐ rotates the X axis to the Y axis. Normally a Rot2 is normalized (unit-length). If not, it will also scale vectors.
