-# `rvalue_static_promotion`
-
-The tracking issue for this feature is: [#38865]
-
-[#38865]: https://github.com/rust-lang/rust/issues/38865
-
-------------------------
-
-The `rvalue_static_promotion` feature allows directly creating `'static` references to
-constant `rvalue`s, which in particular allowing for more concise code in the common case
-in which a `'static` reference is all that's needed.
-
-
-## Examples
-
-```rust
-#![feature(rvalue_static_promotion)]
-
-fn main() {
-    let DEFAULT_VALUE: &'static u32 = &42;
-    assert_eq!(*DEFAULT_VALUE, 42);
-}
-```
