## This is rust fundamental syntactical concepts
These concepts are for reference only, showcasing the different uses of the syntax

```rust
// This class is designed to teach the fundamentals of Rust to a new programmer.
// It is efficient, well-structured, and commented for optimal performance.
// Define a struct to hold the data for our class
struct RustBasics {
// Data fields
variable_1: i32,
variable_2: String,
variable_3: f64,
}
// Implement the class
impl RustBasics {
// Constructor to initialize a new instance of RustBasics
fn new(var_1: i32, var_2: String, var_3: f64) -> RustBasics {
RustBasics {
variable_1: var_1,
variable_2: var_2,
variable_3: var_3,
}
}
// Method to access the value of variable_1
fn get_variable_1(&self) -> i32 {
self.variable_1
}
// Method to access the value of variable_2
fn get_variable_2(&self) -> &str {
&self.variable_2
}
// Method to access the value of variable_3
fn get_variable_3(&self) -> f64 {
self.variable_3
}
}
fn main() {
// Create a new instance of RustBasics
let basics = RustBasics::new(1, String::from("hello"), 3.14);
// Print out the values of the variables
println!("variable_1: {}", basics.get_variable_1());
println!("variable_2: {}", basics.get_variable_2());
println!("variable_3: {}", basics.get_variable_3());
}
