# smartlock-rs
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
// Get the lock's value
let value = lock.get().await;
// Or if the value doesn't implement copy
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
// A user struct that doesn't implement copy
struct User {
name: String,
age: i32,
// ... lots of other things
}
let user = Slock::new(User {
name: "Bob",
age: 32,
// ... lots of other things
});
// Get just the name
// This performs a clone on only the name
// Get just the age
// Extracts only the age, leaving everything else untouched
let age = user.map(|v| v.age).await;
```
