polys is a Rust crate implementing basic polygons as structs, all implementing a trait which gives the basic functions associated with polygons.
Add this to your Cargo.toml
:
toml
[dependencies]
polys = "0.2.0"
The following is the main.rs
file of my test program. It shows the area and perimeter of a rectangle, a triangle, and a circle.
```rust
use polys::{Polygon, Rect, Tri, Circle, Reg};
fn main() { { let poly = Rect::new(12.0, 6.0); println!("{:?}\n area: {}, peri: {}\n", &poly, &poly.area(), &poly.peri()); }
{
let poly = Tri::new(24.0, 30.0, 18.0);
println!("{:?}\n area: {}, peri: {}\n", &poly, &poly.area(), &poly.peri());
}
{
let poly = Circle::new(5.0);
println!("{:?}\n area: {}, peri: {}\n", &poly, &poly.area(), &poly.peri());
}
{
let poly = Reg::new(3.0, 5.0);
println!("{:?}\n area: {}, peri: {}\n", &poly, &poly.area(), &poly.peri());
}
} ```
The output of this program returns the following: ``` Rect { width: 12.0, height: 6.0 } area: 72, peri: 36
Tri { side1: 24.0, side2: 30.0, side3: 18.0 } area: 216, peri: 72
Circle { radius: 5.0 } area: 78.53981633974483, peri: 31.41592653589793
Reg { length: 3.0, sides: 5.0 } area: 15.484296605300704, peri: 15 ```
