ezing

Simple easing functions for Rust

[quad, cubic, quart, quint, sine, circ, expo, elastic, back, bounce] x [in, out, inout]

All functions have the signature fn(f32) -> f32 and expect input ranging from 0.0 to 1.0. Output is generally in the 0.0 to 1.0 range (except for elastic and back, which return values slightly outside). 0.0 always maps to 0.0, and 1.0 always maps to 1.0.

Use 'em to lerp or something:

let current_pos = lerp(ezing::cubic_inout(t), start, end);
