This feature allows you to use inline constant expressions. For example, you can turn this code:

fn add_one(x: i32) -> i32 { x + 1 } const MY_COMPUTATION: i32 = 1 + 2 * 3 / 4; fn main() { let x = add_one(MY_COMPUTATION); }

into this code:

#![feature(inline_const)] fn add_one(x: i32) -> i32 { x + 1 } fn main() { let x = add_one(const { 1 + 2 * 3 / 4 }); }
