Struct cachedb::EntryWriteGuard

pub struct EntryWriteGuard<'a, K, V, const N: usize> where
    K: KeyTraits, { /* private fields */ }

Guard for the write lock. Puts unused entries into the LRU list.

Implementations

impl<'a, K, V, const N: usize> EntryWriteGuard<'a, K, V, N> where
    K: KeyTraits, 

pub fn expire(&mut self)

Mark the entry for expiration. When dropped it will be put in front of the LRU list and by that evicted soon. Use with care, when many entries become pushed to the front, they eventually bubble up again.

pub fn downgrade(self) -> EntryReadGuard<'a, K, V, N>

Downgrade a write lock to a read lock without releasing it.

Trait Implementations

impl<K, V, const N: usize> Deref for EntryWriteGuard<'_, K, V, N> where
    K: KeyTraits, 

type Target = V

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<K, V, const N: usize> DerefMut for EntryWriteGuard<'_, K, V, N> where
    K: KeyTraits, 

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<K, V, const N: usize> Drop for EntryWriteGuard<'_, K, V, N> where
    K: KeyTraits, 

fn drop(&mut self)

Executes the destructor for this type.
