Overview of Rust:

Rust is a general-purpose systems programming language that spans both high level and low level that is statically typed. The benefit of using rust, in general, is that it is a much safer programming language compared to others; Rust checks for all memory accesses so it is impossible to corrupt the memory, meaning that if the program compiles successfully, then it is very unlikely for the program to contain any blindspots for errors. In terms of Rust’s syntax, it is quite similar to C as shown in the following:

//Filename: src/main.rs
//Functions in Rust starts with 'fn' followed by the function name and then a 
//set of parentheses.

fn main() {
    print_labeled_measurement(5, 'h');
}

fn print_labeled_measurement(value: i32, unit_label: char) {
    println!("The measurement is: {}{}", value, unit_label);
}

Rust also comes with its own build system and package manager called 'Cargo'. Cargo can be thought of as a compiler where it can build the code, but it can also download the libraries that the code needs as well as build these libraries, and these libraries are called dependencies.

Moreover, just like other programming languages, Rust also has the four main scalar data types: integers, floating-point numbers, booleans, and characters. Rust consists of two compound types which are a tuple style and an array type. The difference is that a tuple can have elements that are not the same data type.

Tuple example

fn main() {

    //Creates the tuple x and makes new variables 
    //for each element by using their respective indices
    let x: (i32, f64, u8) = (500, 6.4, 1); 

    //The first element starts from index 0 similar to other programming languages
    let five_hundred = x.0; 

    let six_point_four = x.1;

    //The syntax to access an index of a tuple is 'tuple''period''index' as shown
    let one = x.2;
}

What is Rust’s used for?

Rust can be used for topics such as operating system development, web services, command-line tools and others. Rust is an ideal programming language for those who seek efficiency and security. Rust is also very good for concurrency and memory safe.
