-/// A trait for borrowing data.
-///
-/// In general, there may be several ways to "borrow" a piece of data.  The
-/// typical ways of borrowing a type `T` are `&T` (a shared borrow) and `&mut T`
-/// (a mutable borrow). But types like `Vec<T>` provide additional kinds of
-/// borrows: the borrowed slices `&[T]` and `&mut [T]`.
-///
-/// When writing generic code, it is often desirable to abstract over all ways
-/// of borrowing data from a given type. That is the role of the `Borrow`
-/// trait: if `T: Borrow<U>`, then `&U` can be borrowed from `&T`.  A given
-/// type can be borrowed as multiple different types. In particular, `Vec<T>:
-/// Borrow<Vec<T>>` and `Vec<T>: Borrow<[T]>`.
-///
-/// If you are implementing `Borrow` and both `Self` and `Borrowed` implement
-/// `Hash`, `Eq`, and/or `Ord`, they must produce the same result.
-///
-/// `Borrow` is very similar to, but different than, `AsRef`. See
-/// [the book][book] for more.
