Struct eyeball::WeakObservable

pub struct WeakObservable<T, L: Lock = SyncLock> { /* private fields */ }

A weak reference to a SharedObservable.

This type is only useful in niche cases, since one generally shouldn’t nest interior-mutable types in observables, which includes observables themselves.

See std::sync::Weak for a general explanation of weak references.

Implementations

impl<T, L: Lock> WeakObservable<T, L>

pub fn upgrade(&self) -> Option<SharedObservable<T, L>>

Attempt to upgrade the WeakObservable into a SharedObservable.

Returns None if the inner value has already been dropped.
