Struct GlobalLockedBy

Source 
pub struct GlobalLockedBy<T: ?Sized, B: GlobalLockBackend> { /* private fields */ }
Expand description

A version of LockedBy for a GlobalLock.

See global_lock! for examples.

Implementations§

Source§

impl<T, B: GlobalLockBackend> GlobalLockedBy<T, B>

Source

pub fn new(val: T) -> Self

Create a new GlobalLockedBy.

The provided value will be protected by the global lock indicated by B.

Source§

impl<T: ?Sized, B: GlobalLockBackend> GlobalLockedBy<T, B>

Source

pub fn as_ref<'a>(&'a self, _guard: &'a GlobalGuard<B>) -> &'a T

Access the value immutably.

The caller must prove shared access to the lock.

Source

pub fn as_mut<'a>(&'a self, _guard: &'a mut GlobalGuard<B>) -> &'a mut T

Access the value mutably.

The caller must prove shared exclusive to the lock.

Source

pub fn get_mut(&mut self) -> &mut T

Access the value mutably directly.

The caller has exclusive access to this GlobalLockedBy, so they do not need to hold the lock.
