Struct spin::mutex::spin::SpinMutexGuard

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

This is supported on crate features mutex and spin_mutex only.

A guard that provides mutable data access.

When the guard falls out of scope it will release the lock.

Implementations

impl<'a, T: ?Sized> SpinMutexGuard<'a, T>

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

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

Note that this function will permanently lock the original SpinMutex.

let mylock = spin::mutex::SpinMutex::<_>::new(0);

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

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