This new constructor allows creating mutexes, reentrant mutexes and RwLocks in a constant context on stable Rust by manually passing in the underlying raw mutex / rwlock.
This adds various helper functions to `parking_lot` that allow creating parking_lot's mutexes, reentrant mutexes, fair mutexes and RwLocks in constant contexts on stable Rust.

This is a rough initial implementation. I'm not sure if the helpers in |

Can you make two changes:
- Put

new_*toconst_*to make it clear that they are mainly useful for const initializers.
This splits the doc comments into multiple paragraphs and renames the helpers to create the locking primitives to `const_*` instead of `new_*`.

217: Implement Support for creating the locking primitives in a const context on stable Rust r=Amanieu a=CryZe This adds a new constructor `const_new` to lock_api's mutexes, reentrant mutexes and RwLocks that allows creating them in a constant context on stable Rust by manually passing in the underlying raw mutex / rwlock. Additionally, various helper functions are being added to parking_lot that allow creating mutexes, reentrant mutexes, fair mutexes and RwLocks in constant contexts on stable Rust.

Any chance this could get cut in a release? I could probably deprecate https://crates.io/crates/static_locks if it were. |
