Learning Rust Memory Management

Today I explored Rust's unique ownership and borrowing system. It's fascinating how the compiler ensures memory safety at compile time without a garbage collector.

Key Concepts

1. 1.Each value has an owner
2. 2.There can only be one owner at a time
3. 3.When the owner goes out of scope, the value is dropped

• ▹You can have either one mutable reference OR any number of immutable references
• ▹References must always be valid

Example

fn main() {
    let s1 = String::from("hello");
    let s2 = &s1; // Immutable borrow
    println!("{} {}", s1, s2);
}

This mental model takes time to internalize, but once it clicks, you can write incredibly safe and performant code.
