Struct SpringEasing 

pub struct SpringEasing { /* private fields */ }

Eases a value using a user-defined spring formula.

Implementations

impl SpringEasing

pub fn new() -> Self

Creates a spring easing with all parameters zero.

pub fn with_values( mass: f64, stiffness: f64, damping: f64, initial_velocity: f64, ) -> Self

Creates a spring easing with the given parameters.

pub fn mass(&self) -> f64

The spring mass.

pub fn set_mass(&self, value: f64)

pub fn stiffness(&self) -> f64

The spring stiffness.

pub fn set_stiffness(&self, value: f64)

pub fn damping(&self) -> f64

The spring damping.

pub fn set_damping(&self, value: f64)

pub fn initial_velocity(&self) -> f64

The spring initial velocity.

pub fn set_initial_velocity(&self, value: f64)

Trait Implementations

impl Default for SpringEasing

fn default() -> Self

Returns the “default value” for a type.

impl From<SpringEasing> for Easing

fn from(value: SpringEasing) -> Self

Converts to this type from the input type.

impl IEasing for SpringEasing

fn to_shared(&self) -> Arc<SharedEasing>

The easing as the render thread evaluates it: a key frame animation of the compositor runs there. An easing without parameters returns itself; one with parameters returns a copy with the parameters it has now.

fn ease(&self, progress: f64) -> f64

Returns the transformed value for a linear progress.

fn derives_from_easing(&self) -> bool

Whether the object is an easing class: upstream, a class deriving from the Easing base class, which code tests for with a cast. True for every easing of this module and by default, because implementing this trait is how an easing class is written here; an object that stands for a bare implementation of the contract (not an easing class) answers false.

impl MarkupTyped for SpringEasing

const MARKUP: &'static MarkupType

The markup metadata of the type.

impl PartialEq for SpringEasing

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
