Struct SpringDescription 

pub struct SpringDescription {
    pub mass: f32,
    pub stiffness: f32,
    pub damping: f32,
}

The shared animation layer — physics, curves, driver — see frus_core::animation. Re-exported here so applications can reach it through frus_widgets without depending on frus-core directly. The parameters of a damped spring.

Fields

mass: f32

Mass m (> 0).

stiffness: f32

Stiffness k (> 0).

damping: f32

Damping c (≥ 0).

Implementations

impl SpringDescription

pub fn new(mass: f32, stiffness: f32, damping: f32) -> SpringDescription

A spring given directly as (mass, stiffness, damping).

pub fn with_damping_ratio( mass: f32, stiffness: f32, ratio: f32, ) -> SpringDescription

A spring given by its damping ratio: 1 is critical (the fastest settle with no overshoot), < 1 oscillates, > 1 is sluggish. c = ratio · 2·√(m·k).
