WeakSelf is simple way to have a Weak pointer inside a data structure pointing to itself.


## Use Case


Sometimes you want to create a ```struct``` with a pointer to itself or just some other recursive data structure.


```rust
struct Foo {
    me: &Foo
}

impl Foo {
    pub fn new() -> Foo {
        let foo = Foo{
            me: ????
        };
        foo
    }
}

```

This create helps you do that: 

```rust
pub struct Foo {
    weak_self: WeakSelf<Foo>
}

impl Foo {
    pub fn new() -> Arc<Foo> {
        let foo = Arc::new(Foo{
            weak_self: WeakSelf::new()
        });
        foo.me.init(&foo);
        foo
    }
    
    fn weak(&self) -> Weak<Self> {
        self.weak_self.get()
    }
}

```
