Rust Async Unveiled: The Secret to Making Code ‘Slack Off’ While Doubling Efficiency! Hello, future Rust master! Today we’re diving into a fascinating topic: asynchronous programming (Async). You might have encountered it in JavaScript or Python, thinking of it as a behind-the-scenes hero silently handling everything. But in Rust, this “hero” operates completely differently. It doesn’t play “magic tricks” - everything is laid out in the open, both explicit and efficient, and after compilation, it’s almost “zero-cost”! ...
