Enum PiMutexStateError 

pub enum PiMutexStateError {
    WaiterOwnsLock,
    InvalidState,
}

Failure of a lock-local PI owner-word transition.

Variants

WaiterOwnsLock

The current task attempted to acquire a mutex it already owns.

InvalidState

The owner word or lock generation violates the PI state machine.

impl Error for PiMutexStateError

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
