Crate beef

beef

Alternative implementation of Cow that's more compact in memory.

use beef::Cow;

let borrowed = Cow::borrowed("Hello");
let owned = Cow::from(String::from("World"));

assert_eq!(
    format!("{} {}!", borrowed, owned),
    "Hello World!",
);

// beef::Cow is 3 word sized, while std::borrow::Cow is 4 word sized
assert!(std::mem::size_of::<Cow<str>>() < std::mem::size_of::<std::borrow::Cow<str>>());
