Betterunion

betterunion is crate which provides a safe zero-cost way of storing types as raw data which can later be reinterpreted, only types which implement bytemuck's Pod trait can be used in the read and write functions.

Example:

use betterunion::BetterUnion;

fn main() {
    let mut u = BetterUnion::<8>::new();
    u.write(42u32);
    println!("{}", u.read_copy::<u64>());

    let mut v = BetterUnion::<16>::new();
    v.write(3.14f64);
    println!("{}", v.read_copy::<f64>());
}
