Trait LockQueryExt 

pub trait LockQueryExt<T, L>
where
    L: LockValue<T>,
{
    // Required method
    fn lock_iter(
        &self,
    ) -> Box<dyn Iterator<Item = LockedValueRef<'_, T, L>> + '_>;
}

Extension trait for querying collections of locks.

Provides convenient methods for querying HashMaps and Vecs containing locked values without data copying.

Required Methods

fn lock_iter(&self) -> Box<dyn Iterator<Item = LockedValueRef<'_, T, L>> + '_>

Create an iterator over locked values for querying.

Example

let map: HashMap<String, Arc<RwLock<Product>>> = /* ... */;
let iter = map.lock_iter();
