Struct spinning_top::RawSpinlock

pub struct RawSpinlock { /* fields omitted */ }

Provides mutual exclusion based on spinning on an AtomicBool.

It's recommended to use this type either combination with lock_api::Mutex or through the Spinlock type.

Example

use lock_api::RawMutex;
let lock = spinning_top::RawSpinlock::INIT;
assert_eq!(lock.try_lock(), true); // lock it
assert_eq!(lock.try_lock(), false); // can't be locked a second time
lock.unlock(); // unlock it
assert_eq!(lock.try_lock(), true); // now it can be locked again
