Module sync_guard 

Poison-safe lock accessors.

std::sync locks become poisoned when a thread panics while holding them; afterwards every lock() panics again, permanently breaking the subsystem for the rest of the process lifetime. These helpers recover the guard instead, so one stray panic cannot take down unrelated code.

Functions

mutex_lock

Acquire a mutex guard, recovering from a poisoned lock.

read_lock

Acquire a read guard, recovering from a poisoned lock.

write_lock

Acquire a write guard, recovering from a poisoned lock.
