Struct stakker::ShareWeak

pub struct ShareWeak<T> { /* private fields */ }

Weak reference to a Share

This reference does not stop the Share from being dropped, but can be used to recover a Share reference if it is still alive due to a strong reference held elsewhere.

Implementations

impl<T> ShareWeak<T>

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

If there are still strong references to the shared data, returns a new Share. Otherwise the shared data has been dropped, and so returns None.

pub fn strong_count(&self) -> usize

Return the number of strong references to the shared data

pub fn weak_count(&self) -> usize

Return the number of weak references to the shared data, including this one, or 0 if there are no strong pointers remaining.

Trait Implementations

impl<T> Clone for ShareWeak<T>

fn clone(&self) -> Self

Return another weak reference to the shared data

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
