Trait LockExt 

pub trait LockExt<T> {
    // Required method
    fn lock_or_reset(&self, reset: impl FnOnce(&mut T)) -> MutexGuard<'_, T>;

    // Provided method
    fn lock_or_default(&self) -> MutexGuard<'_, T>
       where T: Default { ... }
}

Locking a Mutex whose state can be thrown away after a panic.

Required Methods

fn lock_or_reset(&self, reset: impl FnOnce(&mut T)) -> MutexGuard<'_, T>

Lock; if a panic poisoned the lock, reset the state first and clear the poison.

Provided Methods

fn lock_or_default(&self) -> MutexGuard<'_, T>

where T: Default,

LockExt::lock_or_reset back to T::default().

Dyn Compatibility

This trait is not dyn compatible.

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