What are you trying to do with the raw locks? You should have everything that you need with the normal Mutex and RwLock types. You can do anything that the raw API can with Mutex<()> and Mutex::force_unlock.
The lock_api is primarily intended for people implementing different lock types that are not based on parking_lot, such as spinlocks and using Linux futexes directly.

I'm trying to implement my own concurrent map (https://pastebin.mozilla.org/9089970) that is generic across lock_api traits. In order to actually use it, or even just test it, I need to have an implementation of RawRwLock, of which I only know parking_lot's one. Obviously, using Mutex<()> will no longer be generic across raw lock implementations.
