Struct ValueRef 

pub struct ValueRef<'a, V, S = RandomState> { /* private fields */ }

ValueRef is returned when invoking get method of the Cache. It contains a RwLockReadGuard and a value reference.

Implementations

impl<'a, V, S: BuildHasher> ValueRef<'a, V, S>

pub fn value(&self) -> &V

Get the reference of the inner value.

pub fn release(self)

Drop self, release the inner RwLockReadGuard, which is the same as drop()

pub fn ttl(&self) -> Duration

Get the expiration time.

impl<'a, V: Copy, S: BuildHasher> ValueRef<'a, V, S>

pub fn read(self) -> V

Get the value and drop the inner RwLockReadGuard.

Trait Implementations

impl<'a, V, S: BuildHasher> AsRef<V> for ValueRef<'a, V, S>

fn as_ref(&self) -> &V

Converts this type into a shared reference of the (usually inferred) input type.

impl<'a, V: Debug, S: BuildHasher> Debug for ValueRef<'a, V, S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, V: Display, S: BuildHasher> Display for ValueRef<'a, V, S>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
