https://redixhumayun.github.io/assets/img/zero-copy/read_write_lifecycle.png
Zero-copy techniques are used in high-performance database engines to eliminate CPU copies between kernel and user space buffers, improving performance under high load. In Rust, this is achieved by using references and lifetimes to create borrowed views into existing bytes, rather than making owned copies, and structuring the API to reflect the underlying invariants.
