angulus-0.4.0 has been yanked.

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

Features

serde: Serialization and deserialization with the serde crate.
rand: Generate random angle with the rand crate.
