19//! Data access synchronization objects.
20//!
21//! These synchronization objects are similar to those in the [`std::sync`](https://doc.rust-lang.org/std/sync/) module, but they prevent data races when dealing with multiple actors (users or programs) instead of multiple threads considered in classic synchronization objects.
22//!
23//! The following is an overview of the available synchronization objects:
24//!
25//! - [`Mutex`]: The Mutual Exclusion mechanism guarantees that during
26//! execution, only a single actor can access data at any given time.
27//! - [`RwLock`]: Provides a mutual exclusion mechanism that allows multiple
28//! readings by different actors while allowing only one writer at the
29//! execution. In some cases, this can be more efficient than a mutex.
