The Rust language has finally stabilized its never type, denoted by "!", after more than two years of work. The change required a small breaking adjustment to previous editions but enables more efficient generic code and clearer semantics for functions that never return.
Background
Rust's never type has existed as an unstable, compiler‑internal feature for years, used to represent code paths that never produce a value.
