It can help avoid issues such as memory leaks, shallow copies, or undesired behaviour due to differences in object states. impulse owners

"Webzero-cost abstraction is an abstraction you couldn't have possibly written better by hand. For instance, Rust's async is a zero-cost abstraction, because even though it does require a runtime, you can't manually write a better impl Future than the one the compiler auto-generates for you when you use async & await (most of the time, at least).
