Crate hv_guarded_borrow 

Heavy Guarded-Borrow - traits for generalizing over guarded borrow operations

Using these traits allows you to write code which generalizes over the type of “guard” that a type like Mutex, RwLock, RefCell, AtomicRefCell, etc. may return.

Traits

NonBlockingGuardedBorrow

Abstracts over non-blocking guarded immutable borrows (for example, RefCell::try_borrow.)

NonBlockingGuardedBorrowMut

Abstracts over non-blocking guarded mutable borrows from behind immutable references (for example, RefCell::try_borrow_mut.)

NonBlockingGuardedMutBorrowMut

Abstracts over non-blocking guarded mutable borrows from behind mutable references (for example, RefCell::get_mut, or calling .write() on an &mut Arc<RwLock<T>>.)
