Struct NullLock

pub struct NullLock<T>
where
    T: ?Sized,
{
    data: UnsafeCell<T>,
}

A pseudo-lock for experimental purposes.

In contrast to a real Mutex implementation, does not protect against concurrent access from other cores to the contained data. This part is preserved for later inspections.

The lock will only be used as long as it is safe to do so, i.e. as long as the kernel is executing single-threaded, aka only running on a single core with interrupts disabled.

Fields

data: UnsafeCell<T>

Trait Implementations

impl<T> Mutex for NullLock<T>

type Data = T

The type of the data that is wrapped by this mutex.

fn lock<'a, R>(&'a self, f: impl FnOnce(&'a mut Self::Data) -> R) -> R

Locks the mutex and grants the closure temporary mutable access to the wrapped data.
