Crate soy

Soy

Rust interpolation library.

Usage

The main trait used for interpolation is [soy::Lerper]. It requires a single method, calculate, which calculates interpolation progression at a given time.

Example implementing linear interpolation, taken directly from soy’s implementation:

struct Linear;

impl soy::Lerper for Linear {
    fn calculate(&self, t: f32) -> {
        t
    }
}

Structs

Bezier

Unit cubic bezier easing function.

Linear

Linear interpolator: f(t) = t.

Constants

EASE

Ease function, same as CSS’s “ease” timing-function.

EASE_IN

Ease in function, same as CSS’s “ease-in” timing-function.

EASE_IN_OUT

Ease in-out function, same as CSS’s “ease-in-out” timing-function.

EASE_OUT

Ease out function, same as CSS’s “ease-out” timing-function.

Traits

Lerper

Trait implemented by all interpolating methods.

Functions

cubic_bezier

Wrapper around Bezier::new.

lerp

Interpolate between two values given an interpolation method.
