Struct pin_weak::sync::PinWeak

pub struct PinWeak<T: ?Sized>(_);

This is a safe wrapper around something that could be compared to Pin<Weak<T>>

The typical way to obtain a PinWeak is to call PinWeak::downgrade

Implementations

impl<T: ?Sized> PinWeak<T>

pub fn downgrade(rc: Pin<Arc<T>>) -> Self

Equivalent function to Arc::downgrade, but taking a Pin<Arc<T>> instead.

pub fn upgrade(&self) -> Option<Pin<Arc<T>>>

Equivalent function to Weak::upgrade, but taking a Pin<Arc<T>> instead.

pub fn strong_count(&self) -> usize

Equivalent to Weak::strong_count

pub fn weak_count(&self) -> usize

Equivalent to Weak::weak_count

pub fn ptr_eq(&self, other: &Self) -> bool

Equivalent to Weak::ptr_eq
