Struct Pure 

pub struct Pure<F>(pub F);

Adapter turning a raw closure Fn(f64) -> T into an Eval segment.

A closure is an anonymous type, so it cannot implement Eval by name; this named wrapper is the lightweight way to write a pure segment from a closure:

let animation = Pure::new(|alpha| Square::new(alpha)).with_duration(2.0);

Named pure animations implement Eval directly and do not need this wrapper.

Tuple Fields

0: F

Implementations

impl<F> Pure<F>

pub fn new(f: F) -> Self

Wrap a closure into an Eval animation segment.

Trait Implementations

impl<T, F> Eval for Pure<F>

where F: Fn(f64) -> T,

type Output = T

Value produced by this evaluator.

fn eval_alpha(&self, alpha: f64) -> T

Evaluate the segment’s content at normalized progress alpha.

fn sim_step(&self) -> Option<f64>

The content resolution declared by iterative segments: 1/N progress per integration step (N declared via Iterative::with_steps).
