Ever since the rise of Agentic A.I., I've found myself moving further and further away from understanding and diving deep into programming languages. Recently, I've decided to rectify this, and so I've been again writing code by hand. In doing so, I came across a rather interesting function in the Rust standard library, one that has an implementation which is exactly zero lines long. Despite this length, however, it happens to still be quite useful, and so I decided to do a deep dive as to how that's even possible. This video is sponsored by Hostinger.
