Rust Programming Tutorials, Guides & Best Practices

• Very fast and performant
• Rich ecosystem with lots of middleware and plugins

Cons:

• Mutable Variables:

let mut x = 5;
x = 6;

Asynchronous programming allows for handling operations that might take time to complete, like I/O-bound tasks, without blocking the main execution thread. Rust’s async model is based on zero-cost abstractions that avoid runtime overhead, making it possible to write highly efficient asynchronous programs.

Rust uses the async and await keywords to define and work with asynchronous operations, enabling non-blocking code execution in a clear and manageable way.

struct ImportantExcerpt<'a> {
    part: &'a str,
}

fn main() {
    let novel = String::from("Call me Ishmael. Some years ago...");
    let first_sentence = novel.split('.').next().expect("Could not find a '.'");
    let i = ImportantExcerpt { part: first_sentence };

    println!("Excerpt: {}", i.part);
}

• Lifetime annotations are crucial in defining how long references in structs or functions must live.
• Multiple lifetime parameters can be used to manage complex relationships between references.
