Enum PiWaitStateError 

pub enum PiWaitStateError {
    WaiterOwnsLock,
    StaleSchedulerOwnership,
    PhysicalOwnerMismatch,
    OwnerlessSelectionMissing,
    ExitedParticipant,
    WaiterAlreadyBlocked,
}

Invariant that rejected a PI waiter graph transition.

Variants

WaiterOwnsLock

A thread attempted to wait on a mutex it already owns.

StaleSchedulerOwnership

The first physical waiter found scheduler ownership left behind.

PhysicalOwnerMismatch

Physical ownership disagrees with the existing scheduler waiter graph.

OwnerlessSelectionMissing

An ownerless physical handoff has no scheduler-selected waiter.

ExitedParticipant

The waiter or physical owner has already exited.

WaiterAlreadyBlocked

The waiter already owns a different PI wait edge.

impl Eq for PiWaitStateError

impl Error for PiWaitStateError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
