Struct polys::Reg

pub struct Reg { /* fields omitted */ }

Struct that represents a regular polygon.

Implementations

impl Reg

pub fn new(l: f64, s: f64) -> Reg

Returns a new Poly based on a given length l and sides s

Examples

let reg = polys::Reg::new(3, 5);

Trait Implementations

impl Debug for Reg

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Polygon for Reg

fn area(&self) -> f64

Gets the area of the Reg.

Examples

let reg  = polys::Reg::new(3, 5);
let area = reg.area();
assert_eq!(area, 15.484296605300704);

This can also be seen by comparing the Rect square and Reg implementations.

let square = polys::Rect::square(7).area();
let reg    = polys::Reg::new(7, 4) .area();
assert_eq!(square, reg);

fn peri(&self) -> f64

Gets the perimeter of the Reg.

Examples

This works on a regular polygon where it has 5 of more sides.

let reg  = polys::Reg::new(3, 5);
let peri = reg.peri();
assert_eq!(peri, 15);

This can also be seen by comparing the Rect square and Reg implementations.

let square = polys::Rect::square(7).peri();
let reg    = polys::Reg::new(7, 4) .peri();
assert_eq!(square, reg);
