Struct MutexGuard

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

A generic guard that will protect some data access and uses either a ticket lock or a normal spin mutex.

For more info see TicketMutexGuard or SpinMutexGuard.

Implementations

impl<'a, T> MutexGuard<'a, T>

where T: ?Sized,

pub fn leak(this: MutexGuard<'a, T>) -> &'a mut T

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

Note that this function will permanently lock the original Mutex.

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

let data: &mut i32 = spin::MutexGuard::leak(mylock.lock());

*data = 1;
assert_eq!(*data, 1);
