# deref\_owned

This crate provides a smart pointer `Owned`, which points to an owned value.
It's similar to `Cow`, except that it's always owning its pointee. Moreover, a
trait `IntoOwned` is provided, which allows conversion of pointers to an owned
value though an `.into_owned()` method. The trait `IntoOwned` is implemented
for:

* `&'a T where T: ?Sized + ToOwned`
* `Cow<'a, T> where T: ?Sized + ToOwned`
* `Owned<T>`
* `Box<T>`

## Changelog

* 2022-06-27: Version 0.2.0
    * Some more trait implementations (`AsRef`, `AsMut`, `Borrow`, `BorrowMut`,
      and `Display`) have been added for `Owned`
      (and `Debug::fmt`'s output is transparent now)
    * `Deref` is now a supertrait of `IntoOwned` and `IntoOwned::Owned` must
      implement `Borrow<<Self as Deref>::Target>`
* 2022-06-26: Version 0.1.0
    * Initial release
