Crate mutable_constant

mutable-constant

This crate provides a smart pointer that allows mutation on immutable values. In most cases, this will behave like a normal smart pointer like Box, but it allows mutation internally when Rust would otherwise forbid it.

Doing this is an unsafe operation. You will need to use unsafe blocks to use this crate effectively.

Example

use mutable_constant::Mc;
 
let mc = Mc::new(42);
let mc_ref = mc.as_ref();
 
assert_eq!(*mc_ref, 42);
 
unsafe {
    *mc.as_defiant_mut() = 43; // This would normally be a compile error
}
 
assert_eq!(*mc_ref, 43);
