The in-memory cache stores have no synchronization mechanisms themselves so they need to be wrapped in your choice of mutex/rwlock if you are using them directly. If you are using them via the macros, then the macros automatically wrap them in the most appropriate synchronization type and the resulting functions are thread-safe.

Is it possible to use the TimedCache with an acquired read lock from the RwLock
? get_cache
requires a mutable self
reference, which means a read lock can't be used here. Any workaround for that? Currently, I am not really able to use the cache in an async environment since all the threads get blocked even on the read operation, which is inefficient because I have to use Mutex
.

Thank you @jaemk
@squadgazzz I think I ran into the same problem. The ref must be mutable probably because evictions are processed during read operations.
