Ang

Ang is a fork of the Angular crate to add various improvements.

Angular types and common helper methods to work with them while using the Rust type system in our favor.

Features

  • Tested and documented,
  • Safety without sacrificing performance and conversion related errors,

Usage

Everything evolves around the Angle<T> type and its two variants Degrees(v) and Radians(v). This ensures proper typing and allows for safe helper methods evolving around it.

extern crate ang;

use angular::*;
use std::f64::consts::{SQRT_2, FRAC_PI_4};

fn calc_hypotenuse(opposite: f64, alpha: Angle) -> f64 {
    opposite / alpha.sin()
}

let a = calc_hypotenuse(SQRT_2, Radians(FRAC_PI_4));
let b = calc_hypotenuse(SQRT_2, Degrees(45.0));
let c = calc_hypotenuse(SQRT_2, Angle::eighth());

assert!((a - 2.0).abs() < 1.0e10);
assert!((a - b).abs() < 1.0e10);
