Typic

Typic helps you transmute fearlessly. It worries about the subtleties of soundness and safety so you don't have to!

Documentation Crates.io

Just import it and replace your #[repr(...)] attributes with #[typic::repr(...)]:

// Import it!
use typic::{self, TransmuteInto};

// Update your attributes!
#[typic::repr(C)]
pub struct Foo(pub u8, pub u16);

// Transmute fearlessly!
let _ : Foo = u32::default().transmute_into(); // Alchemy achieved!
let _ : u32 = Foo::default().transmute_into(); // Compiler Error!
