pub struct Slope<T>
where
    T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero,
{ /* private fields */ }

A simplified slope between two integer points.

Implementations

impl<T> Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero,

pub fn new(horizontal: T, vertical: T) -> Result<Self>

Can return an error if horizontal and vertical are both 0.

let slope = aoclib_rs::point::Slope::new(2, 4).unwrap();
assert_eq!(slope.horizontal(), 1);
assert_eq!(slope.vertical(), 2);

pub fn from_points_2d(pov: &Point2d<T>, other: &Point2d<T>) -> Result<Self>

Can return an error if both points are the same.

use aoclib_rs::point::{Point2d, Slope};
let slope = Slope::from_points_2d(&Point2d::new(0, 0), &Point2d::new(2, 4)).unwrap();
assert_eq!(slope.horizontal(), 1);
assert_eq!(slope.vertical(), 2);

pub fn horizontal(&self) -> T

pub fn vertical(&self) -> T

impl<T> Slope<T>

where T: Copy + DivAssign + NumCast + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero,

pub fn get_angle(&self) -> f64

Returns the angle (from straight up, going clockwise) of the slope in radians.

use aoclib_rs::point::Slope;
assert_eq!(Slope::new(1, 0).unwrap().get_angle(), std::f64::consts::FRAC_PI_2);

Trait Implementations

impl<T> Clone for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + Clone,

fn clone(&self) -> Slope<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + Debug,

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

Formats the value using the given formatter.

impl<T> Hash for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + Hash,

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T> PartialEq for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + PartialEq,

fn eq(&self, other: &Slope<T>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T> Copy for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + Copy,

impl<T> Eq for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero + Eq,

impl<T> StructuralPartialEq for Slope<T>

where T: Copy + DivAssign + PartialOrd + Rem<Output = T> + Sub<Output = T> + Zero,
