Struct stretto::ValueRefMut

source · [−]

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

Expand description

ValueRefMut is returned when invoking get_mut method of the Cache. It contains a RwLockWriteGuard and a mutable value reference.

Implementations

source

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

source

pub fn value(&self) -> &V

Get the reference of the inner value.

source

pub fn value_mut(&mut self) -> &mut V

Get the mutable reference of the inner value.

source

pub fn write(&mut self, val: V)

Set the value

source

pub fn write_once(self, val: V)

Set the value, and release the inner RwLockWriteGuard automatically

source

pub fn release(self)

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

source

pub fn clone_inner(&self) -> V

Clone the inner value

source

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

source

pub fn read(self) -> V
