Struct RwLockReadGuard

pub struct RwLockReadGuard<'a, T: 'a + ?Sized> { /* private fields */ }

A guard that provides immutable data access.

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

Implementations

impl<'rwlock, T: ?Sized> RwLockReadGuard<'rwlock, T>

pub fn leak(this: Self) -> &'rwlock T

Leak the lock guard, yielding a reference to the underlying data.

Note that this function will permanently lock the original lock for all but reading locks.

let mylock = spin::RwLock::new(0);

let data: &i32 = spin::RwLockReadGuard::leak(mylock.read());

assert_eq!(*data, 0);
