Enum MutexProtocol 

pub enum MutexProtocol {
    None,
    Inherit,
    Protect,
}

The protocol to be used with the mutex. See pthread_mutexattr_getprotocol for more information.

Variants

None

The lock-owning thread’s priority is unaffected by the mutex.

Inherit

Available on non-NetBSD only.

The lock-owning thread’s priority is the maximum of its own priority and the priority of all threads waiting on the mutex.

Not available on NetBSD, whose pthread_mutexattr_setprotocol rejects PTHREAD_PRIO_INHERIT with ENOTSUP while accepting the other two protocols.

Protect

Available on neither Android nor musl.

The lock-owning thread’s priority is the maximum of its own priority and the priority ceilings of every mutex it holds that was built with this protocol, whether or not anyone is blocked on them.

Set the ceilings with MutexBuilder::with_priority_ceiling. Not available on musl or Android, neither of which implements the POSIX Thread Priority Protection option: there are no ceilings there for this protocol to read, and both reject it outright.
