A trait providing easing functions for smooth interpolation.

Easing functions take a value t in the range [0, 1] and return an eased value in the same range, useful for animations and transitions.

Supported for scalar types (f32, f64) and SIMD vectors (with nightly feature). See easings.net for visualizations.

fn ease_in_curve<C>(self, curve: C) -> Self

where Self: EasingImplHelper, C: CurveParam<Self>,

Applies custom exponential easing in with a curve parameter.

Accelerates from slow to fast using exponential growth controlled by the curve parameter.

• curve > 0: Convex curve, steeper acceleration (e.g., curve = 1.0 for moderate, curve = 4.0 for sharp).
• curve < 0: Concave curve, gentler acceleration (e.g., curve = -1.0 for soft, curve = -4.0 for very gradual).
• curve ≈ 0: Approximates linear easing.

The curve parameter can be a scalar or SIMD vector matching the easing argument type. Inspired by SuperCollider’s Env curve parameter for envelope shaping. See SuperCollider Env documentation for more on curve values.

fn ease_out_curve<C>(self, curve: C) -> Self

where Self: EasingImplHelper, C: CurveParam<Self>,

Applies custom exponential easing out with a curve parameter.

Decelerates from fast to slow using exponential decay controlled by the curve parameter.

• curve > 0: Convex curve, steeper deceleration.
• curve < 0: Concave curve, gentler deceleration.
• curve ≈ 0: Approximates linear easing.

The curve parameter can be a scalar or SIMD vector matching the easing argument type. Mirrors ease_in_curve but in reverse. Inspired by SuperCollider’s Env curve parameter. See SuperCollider Env documentation.

fn ease_in_out_curve<C>(self, curve: C) -> Self

where Self: EasingImplHelper, C: CurveParam<Self>,

Applies custom exponential easing in-out with a curve parameter.

Accelerates then decelerates using exponential transitions controlled by the curve parameter.

• curve > 0: Sharper acceleration and deceleration.
• curve < 0: Softer transitions.
• curve ≈ 0: Approximates linear easing.

The curve parameter can be a scalar or SIMD vector matching the easing argument type. Combines ease_in_curve and ease_out_curve for smooth bidirectional transitions. Inspired by SuperCollider’s Env curve parameter for envelope shaping. See SuperCollider Env documentation.

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.
