Enum LockError 

pub enum LockError {
    Recursive,
    Timeout,
    TooManyHeldMutexes,
    NotInTask,
    Poisoned,
}

Error returned by PriorityMutex::lock_timeout.

Variants

Recursive

The calling task already holds this mutex (re-entrancy — a self-deadlock).

Timeout

lock_timeout’s deadline passed before the mutex was acquired.

TooManyHeldMutexes

The calling task already holds tcb::MAX_HELD mutexes.

NotInTask

Called outside of a preemptive task context.

Poisoned

The mutex was poisoned: its previous holder faulted while holding it (plan.md §3.4). The data may be inconsistent.
