Angular types and common helper methods to work with them while using the Rust type system in our favor.
- Tested and documented
- Safe while don't sacrificing performance and conversion related errors
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 angular;
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);
