## about.

eazy iS AMONG THE FASTEST, ATOMiC AND ENHANCED `easing functions` KiT WRiTTEN iN RUST FOR CREATiVE, GAMERS, PROGRAMMERS, SCiENTiSTS, ETC WHO CARES ABOUT METRiCS — @see [benchmark](../eazy-notes/docs/benchmark.md).    

eazy iS METiCULOUSLY OPTiMiZED iT'S A PERFECT MATCH FOR PRECiSiON OR SOPHiSTiCATED PROGRAMS — SUCH AS GUi, GAME ENGiNE, PLOTS, WEB AND NATiVE APPLiCATiON.    

> OK-AY, OK-AY — BUT WHY eazy iS OUTPERFORMiNG?

- MiNiMAL OVERHEAD ABSTRACTiON — *inlining, zero vtable lookups.*
- MATHEMATICALLY EFFiCiENT — *no branches, no inttermediate allocations.*
- PROPER BENCHMARK DiSCiPLiNE — *performance matter.*

## example.

```rs
use eazy::Curve;
use eazy::easing::oscillatory::bounce::OutBounce;

fn main() {
  for time in (0..=100).map(|x| x as f32 / 100.0) {
    let bounce = OutBounce.y(time);

    println!("reaction bounce: {bounce:.3}");
  }
}
```

`cargo run -p eazy --example derive-tweenable`

## benches.

> *beat'em up!*

BENCHES ARE DONE iN COMPARiSON BETWEEN `bevy_tween`, `easings`, `emath` (FROM `egui`) , `glissade`, `interpolation`, `keyframe`, `simple-easing2` CRATES. MOST OF THEM ARE FOLLOW THE ROBERT PENNER'S EASiNG FuNCTiONS, THEY ONLY iMPLEMENTED THE BASiCS ONE. REGARDiNG PERFORMANCE SOME OF OuR iMPLEMENTATiONS ARE SLiGHTLY FASTER AND STABLE, SO DEPENDiNG YOUR NEEDED, YOu SHOuLD TRY eazy. THE SAMPLE BELOW CONFiRM THAT OuR EASiNG FuNCTiONS ARE PRETTY WELL OPTiMiZED.
