Trait InterruptibleMutexExt 

pub trait InterruptibleMutexExt<T: ?Sized> {
    // Required method
    fn lock_interruptible<F>(
        &self,
        should_interrupt: F,
    ) -> Result<MutexGuard<'_, T>, PiMutexLockInterrupted>
       where F: FnMut() -> bool;
}

Linux rtmutex-style interruptible acquisition for a PI mutex.

Required Methods

fn lock_interruptible<F>( &self, should_interrupt: F, ) -> Result<MutexGuard<'_, T>, PiMutexLockInterrupted>

where F: FnMut() -> bool,

Acquires this mutex unless should_interrupt becomes true while the caller remains queued.

A published ownerless handoff wins over interruption. The returned guard therefore has the same acquire-before-signal ordering as Linux mutex_lock_interruptible() under PREEMPT_RT. The interruption publisher must also wake the waiting task, just as Linux signal_wake_up_state() sets TIF_SIGPENDING and wakes TASK_INTERRUPTIBLE; this predicate is not polled while the task is asleep.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
