points

Data structure for representing a pair of coordinates of float type. The structure supports the same sets of linear algebra operation from vectors for a R² space:

• Point addition
• Scalar point addtition
• Point subtraction
• Scalar point subtraction
• Point scalar multiplication
• Point scalar division
• Euclidean distance
• Squared euclidean distance
• Euclidean norm

Usage

• Install

cargo add points

• Expressions

// execute (a + b) * 3 + (a - c)
let p1: Point = Point::default();
let p2 = Point::new(1.0, 3.0);
let p3 = Point::new(1.5, 2.5);
let result = (p1 + p2) * 3.0 + (p1 - p3);
assert_eq!(Point::new(1.5, 6.5), result);

// squared euclidean distance
let p1 = Point::new(1.0, 3.0);
let p2 = Point::new(1.5, 2.0);
let expected = 1.25;
let result = p1.squared_distance_to(p2);
assert_eq!(expected, result);

// euclidean distance
let p1 = Point::new(1.0, 3.0);
let p2 = Point::new(1.5, 2.0);
let expected = 1.118033988749895;
let result = p1.distance_to(p2);
assert_eq!(expected, result);
