A simple spinlock crate based on the abstractions provided by [`lock_api`].

[`lock_api`]: https://docs.rs/lock_api/

## Example

First, import the crate as a dependency in your `Cargo.toml`. Then you can use it in the following way:

```rust
use spinning_top::Spinlock;

fn main() {
    // Wrap some data in a spinlock
    let data = String::from("Hello");
    let spinlock = Spinlock::new(data);
    make_uppercase(&spinlock); // only pass a shared reference
    // We have ownership of the spinlock, so we can extract the data without locking
    // Note: this consumes the spinlock
    let data = spinlock.into_inner();
    assert_eq!(data.as_str(), "HELLO");
}

fn make_uppercase(spinlock: &Spinlock<String>) {
    // Lock the spinlock to get a mutable reference to the data
    let mut locked_data = spinlock.lock();
    assert_eq!(locked_data.as_str(), "Hello");
    locked_data.make_ascii_uppercase();

    // the lock is automatically freed at the end of the scope
}
```
