Struct EntryByRef

pub struct EntryByRef<'a, 'b, K, Q, V>
where
    K: Borrow<Q> + Eq + Hash + Clone,
    Q: Eq + Hash + ?Sized,
{
    pub key: &'b Q,
    pub value: &'a mut Option<V>,
    /* private fields */
}

An RAII guard providing exclusive access to a key-value pair in the LockMap.

When dropped, this type automatically unlocks the entry allowing other threads to access it.

Type Parameters

• 'a - Lifetime of the LockMap
• 'b - Lifetime of the key reference
• K - Key type that must implement Eq + Hash + Clone
• Q - Query type that can be borrowed from K
• V - Value type

Examples

use lockmap::LockMap;

let map = LockMap::new();
{
    // Get exclusive access to an entry
    let mut entry = map.entry("key");

    // Modify the value
    entry.value.replace(42);

    // Entry is automatically unlocked when dropped
}

Fields

key: &'b Q

value: &'a mut Option<V>
