BorrowBag

A type-safe, heterogeneous collection with zero-cost add and borrow.

BorrowBag allows the storage of any value, and returns a Handle which can be used to borrow the value back later. As the BorrowBag is add-only, Handle values remain valid for the lifetime of the BorrowBag.

For usage details, please see the documentation

Motivation

BorrowBag solves the problem of assembling Gotham's Middleware and Pipeline structures, storing concrete types without losing their type information, and with an ability to borrow them back later after moving the collection.

The Gotham project extracted the implementation into this crate for use in other contexts and continues to maintain it.
