A mutex for Rust that never deadlocks.
A Slock, or Smart Lock, is a smart wrapper around an atomically reference counted read/write lock.
All accesses and modifications are done in a contained manner. This ensures that threads will never deadlock on a Slock operation.
```rust // Create a new lock with an initial value let lock = Slock::new(5i32);
// Change the lock's value lock.set(|v| v + 1).await;
// Get the lock's value if Copy let value = lock.get().await; // Get the lock's value if Clone let value = lock.get_clone().await;
assert_eq!(value, 6); ```
It's also possible to extract only the data you need from larger structures without the need to clone the entire thing.
```rust struct User { name: String, age: i32, }
let user = Slock::new(User { name: "Bob", age: 32, });
// Extract something that is Copy let age = user.map(|v| v.age).await;
// Extract something that is Clone let name = user.map(|v| v.name.clone()).await;
// Increment age by 1
user.set(|v| v.age += 1).await;
```
