Struct sunrise_kernel::sync::SpinRwLockReadGuard

pub struct SpinRwLockReadGuard<'a, T> where
    T: 'a + ?Sized,  {
    lock: &'a AtomicUsize,
    data: NonNull<T>,
}

A guard from which the protected data can be read

When the guard falls out of scope it will decrement the read count, potentially releasing the lock.

Fields

lock: &'a AtomicUsize

data: NonNull<T>

Trait Implementations

impl<'a, T> Debug for RwLockReadGuard<'a, T> where
    T: 'a + Debug + ?Sized, 

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

Formats the value using the given formatter.

impl<'rwlock, T> Deref for RwLockReadGuard<'rwlock, T> where
    T: ?Sized, 

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<'rwlock, T> Drop for RwLockReadGuard<'rwlock, T> where
    T: ?Sized, 

fn drop(&mut self)

Executes the destructor for this type.

impl<'a, T> Lock<'a, RwLockReadGuard<'a, T>> for SpinRwLock<T>

fn lock(&self) -> SpinRwLockReadGuard<T>

Locks the lock until the returned guard is dropped. The actual semantics is up to the underlying lock. This trait does not make any guarantee about anything like memory ordering or whatnot. Please read the documentation of the underlying lock type.
