Trait MutexExt

pub trait MutexExt<T>: Sealed {
    // Required method
    fn lock_py_attached(&self, py: Python<'_>) -> LockResult<MutexGuard<'_, T>>;
}

Extension trait for std::sync::Mutex which helps avoid deadlocks between the Python interpreter and acquiring the Mutex.

Required Methods

fn lock_py_attached(&self, py: Python<'_>) -> LockResult<MutexGuard<'_, T>>

Lock this Mutex in a manner that cannot deadlock with the Python interpreter.

Before attempting to lock the mutex, this function detaches from the Python runtime. When the lock is acquired, it re-attaches to the Python runtime before returning the LockResult. This avoids deadlocks between the GIL and other global synchronization events triggered by the Python interpreter.
