This course provides the best approach to learn Rust, starting from the basics and advancing to complex topics. It is an introduction to Rust for beginners aspiring to become skilled Rust developers.

The word is out: developers love Rust. It's rapidly becoming a top choice for systems and embedded programmers, and the demand for Rust developers is rising. Known for its performance, reliability, and productivity—especially compared to C++—Rust is a powerful language to master. If you're a systems developer, it's a fantastic next step.
In this course, you'll learn Rust by actively engaging in coding. You’ll start with a simple "Hello world" program and cover essential concepts like arrays, strings, vectors, enums, structures, traits, generics, functions, and logic. You'll also dive into advanced topics such as lifetime and memory management.
By the end of this course, you'll have a solid foundation in Rust programming and be well-prepared to take on more advanced concepts, making it ideal for Rust beginners looking to become proficient Rust developers.

Rust Programming Language

fn fibonacci(term: i32) -> i32 {
    match term {
        0 =>  0,
        1 =>  1,
        _ => fibonacci(term-1) + fibonacci(term-2),
    }
}
fn main(){
    println!("fibonacci(4)={}",fibonacci(4));
}

## Explanation
A recursive function, `fibonacci`, takes a **parameter `term` of type i32** and **returns** an integer of type `i32`, i.e., the nth term of the Fibonacci number.

The recursive function has two parts: the base case, and the recursive case.
  * **base case**
    * `match` takes the `term` and if it matches with 0 it returns 0
    and if it matches with 1 it returns 1
  *   **recursive case**
      * It decrements the value of the `term` by 1. A recursive call is made with argument `term - 1` or `term - 2` and that the function execution can’t proceed until the recursive calls return. Now the answer before the `+` operator is calculated.
      * It then decrements the value of the `term` by 2. A recursive call is made with argument `term - 1` or `term - 2` and that the function execution can’t proceed until the recursive calls return. Now the answer after the `+` operator is calculated.
       * It simply adds the two values and returns the result.
 

   The following illustration explains the code through a recursion tree:

   > **Note:** This is a binary recursion since the function makes two recursive calls to itself when invoked.
