## vector_operations |
||||||
|
|
||||||
|
### Instructions |
||||||
|
|
||||||
|
Define the structures ThreeDvector that represents a 3 dimensional vector in (for convention in physics the vector are represented as ai + bj + ck where a, b, and c are real numbers and i, j and k represent the direction x,y and z respectively in the Cartesian plane there for we use the names i, j and k for the fields in the ThreeDVector structure |
||||||
|
|
||||||
|
Look how the operations Addition and Subtraction work for a 3 dimensional vector and implement them by implementing the std::ops::Add and std::ops::Sub traits |
||||||
|
|
||||||
|
### Expected Functions and Structures |
||||||
|
|
||||||
|
```rust |
||||||
|
#[derive(Debug, Copy, Clone, PartialEq)] |
||||||
|
pub struct ThreeDVector<T> { |
||||||
|
pub i: T, |
||||||
|
pub j: T, |
||||||
|
pub k: T, |
||||||
|
} |
||||||
|
|
||||||
|
use std::ops::{Add, Sub}; |
||||||
|
|
||||||
|
impl Add for ThreeDVector<T> { |
||||||
|
} |
||||||
|
|
||||||
|
impl Sub for ThreeDVector<T> { |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
### Usage |
||||||
|
|
||||||
|
Here is a program to test your function. |
||||||
|
|
||||||
|
```rust |
||||||
|
use vector_operations::ThreeDVector; |
||||||
|
|
||||||
|
fn main() { |
||||||
|
let a = ThreeDVector { i: 3, j: 5, k: 2 }; |
||||||
|
let b = ThreeDVector { i: 2, j: 7, k: 4 }; |
||||||
|
println!("{:?}", a + b); |
||||||
|
} |
||||||
|
``` |
||||||
|
|
||||||
|
And its output |
||||||
|
|
||||||
|
```console |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ cargo run |
||||||
|
ThreeDVector { i: 5, j: 12, k: 6 } |
||||||
|
student@ubuntu:~/[[ROOT]]/test$ |
||||||
|
``` |
