🧺 own

Wraps an owned or borrowed value.

This allows you to hold either an owned or borrowed value, allowing your data type to be either 'static or 'temporary.

There is a OwnedOrRef::reborrow method that allows the value to be borrowed with a shorter lifetime.

Usage

Add the following to Cargo.toml

own = "0.1.1"

Examples

use own::OwnedOrRef;

fn print(name: OwnedOrRef<'_, String>) {
    println!("{}", *name);
}

fn main() {
    let name = String::from("owned");
    print(name.into());

    let name = &String::from("borrowed");
    print(name.into());
}

use own::OwnedOrMutRef;

fn make_uppercase(name: &mut OwnedOrMutRef<'_, String>) {
    name.make_ascii_uppercase();
}

fn main() {
    let name = String::from("owned");
    let mut owned = name.into();
    make_uppercase(&mut owned);
    assert_eq!("OWNED", *owned);

    let name = &mut String::from("borrowed");
    let mut borrowed  = name.into();
    make_uppercase(&mut borrowed);
    assert_eq!("BORROWED", *borrowed);
}
