WeakSelf

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 }

impl Foo { pub fn new() -> Arc { let foo = Arc::new(Foo{ weak_self: WeakSelf::new() }); foo.me.write(&foo); foo }

fn weak(&self) -> Weak<Self> {
    self.weak_self.get()
}

}

```

This package depends on std only

To use WeakSelf, add this to your Cargo.toml:

toml [dependencies] weakself = "1.0.0"
