A simplified trait for types that can be animated

This trait leverages standard Rust operator traits for mathematical operations, reducing boilerplate and making implementations more intuitive. Only requires implementing interpolation and magnitude calculation.

Required Methods

fn interpolate(&self, target: &Self, t: f32) -> Self

Interpolates between self and target using t (0.0 to 1.0)

fn magnitude(&self) -> f32

Calculates the magnitude/distance from zero Used for determining animation completion

Provided Methods

fn epsilon() -> f32

Returns the epsilon threshold for this type Default implementation provides a reasonable value for most use cases

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.
