Struct WeakSharedContainer

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

A weak reference to a SharedContainer.

This struct provides an abstraction over different weak reference types:

• Weak<std::sync::RwLock<T>> (used in standard multi-threaded environments)
• Weak<tokio::sync::RwLock<T>> (used for async/await support)
• Weak<RefCell<T>> (used in single-threaded environments like WebAssembly)

Weak references don’t prevent the value from being dropped when no strong references remain. This helps break reference cycles that could cause memory leaks.

Implementations

impl<T> WeakSharedContainer<T>

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

Attempts to create a strong SharedContainer from this weak reference.

This will succeed if the value has not yet been dropped, i.e., if there are still other strong references to it.

Returns

• Some(SharedContainer<T>): If the value still exists
• None: If the value has been dropped
