Day 4: Exploring Rust's Compound Data Types

Greetings, fellow coders! 🚀 On Day 4 of my #100DaysOfCode adventure with Rust, I delved into the fascinating world of compound data types – Tuples and Arrays. Let's unravel the key properties and differences between these structures.

Tuples: A Symphony of Heterogeneity

Tuples in Rust serve as harmonious ensembles, allowing the storage of heterogenous data types. Here are some key properties:

• Fixed Length: Tuples maintain a fixed length, ensuring structural integrity.

• Diverse Data Types: They embrace diversity, accommodating elements of different data types.
  

let tup: (i32, f64, u8) = (500, 6.4, 1);

• Accessing Elements: Elements are accessed using the dot operator . along with the index.

let tup: (i32, i32, i32) = (1, 2, 3);
let first = tup.0; // 1
let second = tup.1; // 2
let third = tup.2; // 3

• Destructuring Magic: Tuples can be deconstructed to unveil individual elements.

let tup = (1, 2, 3);
let (x, y, z) = tup;
println!("The value of x is {x}, the value of y is {y}, the value of z is {z}");
// The value of x is 1, the value of y is 2, the value of z is 3

Note: An empty tuple without any values has a special name – unit (), representing empty values or an empty return type.

Arrays: Stacking Homogeneity

Arrays in Rust provide a stack-based haven for homogenous data types. Here's a glimpse of their characteristics:

• Fixed Length: Arrays uphold a fixed length, ideal for scenarios with a predetermined number of elements.

• Homogeneous Storage: They store similar data types, ensuring consistency.
  

let a = [1, 2, 3, 4, 5];
let first = a[0]; // 1
let second = a[1]; // 2

• Destructuring Arrays: Similar to tuples, arrays can be destructured to extract individual elements.

let a = [1, 2];
let [first, second] = a;
println!("The value of first is {first}, the value of second is {second}");
// The value of first is 1, the value of second is 2

Differences and Similarities

Differences:

1. Arrays are homogenous; tuples are heterogenous.

2. Tuples are stored in heap memory; arrays are stored in stack memory.

3. Elements of an array are stored in contiguous memory locations.

4. Tuples are initialized using parentheses (), while arrays use square brackets [].

Similarities:

1. Both have a fixed length.

2. Both support destructuring.

3. Both are used to store multiple values.

4. Both are stored in stack memory.

5. Individual elements can be accessed using indices.
