Trait geo::algorithm::rotate::Rotate

pub trait Rotate<T> {
    fn rotate(&self, angle: T) -> Self
    where
        T: Float;
}

Required Methods

fn rotate(&self, angle: T) -> Self where
    T: Float, 

Rotate a Geometry around its centroid by an angle, in degrees

Positive angles are counter-clockwise, and negative angles are clockwise rotations.
