Stack and Heap in Rust

Rust primarily uses two memory regions: the Stack and the Heap. Understanding how these regions work helps in writing efficient and safe Rust programs.

1. Understanding the Stack

The Stack is a region of memory that operates in a Last In, First Out (LIFO) manner. It is fast, automatically managed, and does not require manual memory allocation.

Characteristics of the Stack:

• Memory is allocated and deallocated automatically
• Fast access due to predictable memory layout
• Limited in size, ideal for small/fixed-size data
• Stores function calls, local variables, and arguments

Example:

fn main() {
    let x: i32 = 10;  // Stack-allocated
    let y: i32 = 20;  // Stack-allocated
    println!("Sum: {}", x + y);
}
