Box-on-write
============

Previously, this crate offered a boxed version of `Cow` that would box values
instead of converting them to a different type like `Vec` or `String`. Due to
the previous implementation, a lack of desire for use, and breakage due to [Rust
issue #46205](https://github.com/rust-lang/rust/issues/46205), this crate is no
longer maintained. The latest version of this crate, 2.0.1, exports no code and
clarifies that it should not be used.
