pub const MUTEX_POISONED: &str = "Mutex poisoned";Expand description
Message for when a mutex guard cannot be acquired due to poisoning.
Mutex guards should use expect rather than handle poison errors.
A poisoned mutex indicates a thread panicked while holding the lock,
meaning protected data may be in an inconsistent state. Propagating
the panic is the idiomatic and safe approach, as continuing with
potentially corrupted data would violate safety invariants.
