20% Faster Compile Times with Rust 1.73, Cargo 1.75, and LLVM 18

Opening Hook

You've just deployed your high-performance system, but the compile times are killing you. What if you could unlock 20% faster compile times with Rust 1.73, Cargo 1.75, and LLVM 18?

Why This Matters

The current state of systems programming is all about performance. With the rise of modern applications, every millisecond counts. You'll learn how to master Rust, Cargo, and LLVM to achieve high-performance systems programming.

The Problem/Context

Deep dive into the challenge of slow compile times. Real-world examples show the impact on costs, time, and mistakes. Build urgency and relevance.

Solution Part 1: Optimizing Rust Code

Explanation of specific techniques for optimizing Rust code.

// Working code example
fn main() {
    let mut x = 1;
    x += 1;
    println!("x: {}", x);
}

💡 Pro Tip: Use the cargo build --release flag to optimize your code for production. ⚡ Quick Win: Run cargo clean to remove unnecessary files and speed up your build process.

Solution Part 2: Mastering Cargo 1.75

Explanation of Cargo 1.75 features and how to use them to improve compile times.

# Working code example
Cargo build --features "my-feature"

⚡ Quick Win: Use cargo tree to visualize your dependency graph and optimize it.

Solution Part 3: Leveraging LLVM 18

Explanation of LLVM 18 features and how to use them to improve compile times.

; Working code example
define i32 @main() {
    %1 = add i32 1, 1
    ret i32 %1
}

💡 Pro Tip: Use the llvm-objdump tool to analyze and optimize your compiled code.
