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