Trait MutexExt 

pub trait MutexExt<T: ?Sized> {
    // Required method
    fn lock_adopting(&self) -> MutexGuard<'_, T>;
}

Locking for a std mutex whose data no holder can leave half-updated.

For such data the poison carries no information, so code that must not panic, such as a drop running during an unwind, can still take the lock.

Required Methods

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

Take the lock, adopting a poisoned one.

The poison only records that some holder panicked, so adopting it is correct only where no holder can panic midway through an update. A thread relocking a mutex it already holds may still panic or deadlock, as under lock.

Dyn Compatibility

This trait is dyn compatible.

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