# `cfg_version` The tracking issue for this feature is: [#64796] [#64796]: https://github.com/rust-lang/rust/issues/64796 ------------------------ The `cfg_version` feature makes it possible to execute different code depending on the compiler version. It will return true if the compiler version is greater than or equal to the specified version. ## Examples ```rust #![feature(cfg_version)] #[cfg(version("1.42"))] // 1.42 and above fn a() { // ... } #[cfg(not(version("1.42")))] // 1.41 and below fn a() { // ... } fn b() { if cfg!(version("1.42")) { // ... } else { // ... } } ```
