Trait tween::TweenValue

pub trait TweenValue: Copy + Debug + Add<Output = Self> + Sub<Output = Self> {
    // Required method
    fn scale(self, scale: f32) -> Self;
}

A TweenValue is a value which can be Tweened. The library fundamentally outputs TweenValue eventually.

If you want to implement your own values to be tweened (for example, your favorite color lib), then you’ll need to implement this trait.

For now, we require Copy, but can reduce this to a Clone implementation. Please file an issue if that is needed for your workflow.

Required Methods

fn scale(self, scale: f32) -> Self

This should be implemented as a simple multiplication. For f64, for example, it’s implemented as (self as f32 * scale) as f64.

Object Safety

This trait is not object safe.
