Rust's derive macros often imply inline code expansion
Original: Rust's derive often implies inline https://yossarian.net/til/post/rust-s-derive-often-implies-inline/ # Rust # Programmi
A new technical write-up examines how Rust's derive macros often imply inlining, expanding code directly at the call site rather than behaving like ordinary functions. The piece, published on a 'today I learned' blog, highlights a subtlety that can surprise developers reasoning about performance and code size. Programmers are sharing it as a useful reminder of how compiler machinery works under the hood.
Why now: Developers enjoy discovering non-obvious compiler behaviours in a widely used language like Rust.
