Struct WeakPool 

pub struct WeakPool<M: Manager, W: From<Object<M>> = Object<M>> { /* private fields */ }

A weak reference to a Pool<T>, used to avoid keeping the pool alive.

WeakPool<T> is analogous to std::sync::Weak<T> for Pool<T>, and is typically used in situations where you need a non-owning reference to a pool, such as in background tasks, managers, or callbacks that should not extend the lifetime of the pool.

This allows components to retain a reference to the pool while avoiding reference cycles or prolonging its lifetime unnecessarily.

To access the pool, use WeakPool::upgrade to attempt to get a strong reference.

Implementations

impl<M: Manager, W: From<Object<M>>> WeakPool<M, W>

pub fn upgrade(&self) -> Option<Pool<M, W>>

Attempts to upgrade the WeakPool to a strong Pool<T> reference.

If the pool has already been dropped (i.e., no strong references remain), this returns None.

Trait Implementations

impl<M: Debug + Manager, W: Debug + From<Object<M>>> Debug for WeakPool<M, W>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
