# BoCell
This is a simple Rust crate which implements a borrowing Cell variant.
In some cases where the internal mutability and reference properties of a RefCell is required it is
advantageous to coerce that Cell from a reference on a temporary basis rather than storing the data as
contained in a RefCell and constantly contending with the runtime borrow-checking RefCells employ.
BoCell is a RefCell which borrows its contents from a `&mut` while in scope. This allows for
non-overlapping mutable borrows to be taken simultaneously from behind a single `&mut`.
## Features
This is a one track crate. `BoCell` can be created from a `&mut` and may be mutably borrowed from
once at a time as a `RefMut`.
`RefMut` implement both `Deref` traits and so can be used like any other reference in terms of
method calls. `RefMut` can also be manipulated by it's associated functions `RefMut::map()`
subreferences, `RefMut::split_tuple()`, and `RefMut::split_triple()` split the reference into 2 and 3
parts. Be mindful when splitting `RefMut`s, having two overlapping mutable borrows active at once is
undefined behaviour.
