Enum MutexThreadTerminationBehavior 

#[repr(i32)]
pub enum MutexThreadTerminationBehavior {
    StallWhenLocked = 0,
    ReleaseWhenLocked = 1,
}

Defines the behavior when a mutex owning thread is terminated

Variants

StallWhenLocked = 0

The mutex stays locked, is unlockable and no longer usable. This can also lead to a mutex leak in the drop.

ReleaseWhenLocked = 1

It implies the same behavior as MutexType::WithDeadlockDetection. Additionally, when a mutex owning thread/process dies the mutex is put into an inconsistent state which can be recovered with Mutex::make_consistent(). The inconsistent state is detected by the next instance which calls Mutex::try_lock() or Mutex::timed_lock().

Important: If the owner dies after another thread has already locked the Mutex it may become impossible to recover the Mutex. Therefore, this feature should be used only in combination with either Mutex::try_lock or Mutex::timed_lock() and never with Mutex::lock().

This is also known as robust mutex.

Trait Implementations

impl Clone for MutexThreadTerminationBehavior

fn clone(&self) -> MutexThreadTerminationBehavior

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MutexThreadTerminationBehavior

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for MutexThreadTerminationBehavior

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MutexThreadTerminationBehavior

fn eq(&self, other: &MutexThreadTerminationBehavior) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
