SLoC
angulus
Unit agnostic angle.
What problem does it solve ?
Using simple floating point numbers to store an angle value is error-prone : you may add two angle with one in radians and the second in degrees or you may try to compute the cosine of a value in degrees and get an unexpected result.
angulus
provides a type that represent an angle with no specific unit.
Example
use angulus::prelude::*;
// Create an angle of 90°.
let alpha = 90.0_f32.deg();
// Create an angle of π/4 rad (45°).
let beta = Angle::RAD_FRAC_PI_4;
// Add the two angle without worrying about units.
let gamma = alpha + beta;
// Print the result.
println!(
"The cosine of {} is {}",
Degrees(gamma), // The angle is wrapped to display the value in degrees.
gamma.cos() // Compute the cosine without worrying about units.
);
// Output : The cosine of 135° is -0.70710677
