## lalgebra_scalar
|
||
|
|
|
||
|
|
### Instructions
|
||
|
|
|
||
|
|
A scalar type must implement the operations Addition, Subtraction, Multiplication and Division (you might also have to use more restrictions). For this use a trait inheritance (supertraits)
|
||
|
|
|
||
|
|
Another condition for a number to be a scalar is to have a zero (neutral element in the addition) and a one (neutral element in the multiplication). Therefore the Scalar trait will require 2 functions zero() and one()
|
||
|
|
|
||
|
|
After finishing implement the Scalar trait for u32, u64, i32, i64, f32, f64
|
||
|
|
|
||
|
|
### Expected Function
|
||
|
|
|
||
|
|
```rust
|
||
|
|
pub trait Scalar: _ {
|
||
|
|
type Item;
|
||
|
|
fn zero() -> Self::Item;
|
||
|
|
fn one() -> Self::Item;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
Here is a program to test your function.
|
||
|
|
|
||
|
|
```rust
|
||
|
|
fn main() {
|
||
|
|
println!("{:?}", f64::zero());
|
||
|
|
println!("{:?}", i32::zero());
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
And its output
|
||
|
|
|
||
|
|
```console
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$ cargo run
|
||
|
|
0.0
|
||
|
|
0
|
||
|
|
student@ubuntu:~/[[ROOT]]/test$
|
||
|
|
```
