Struct LockGuard

Source 
pub struct LockGuard<'a, T> {
    lock: &'a Lock<T>,
    marker: PhantomData<&'a mut T>,
    mode: Mode,
}
Expand description

A guard holding mutable access to a Lock which is in a locked state.

Fields§

§lock: &'a Lock<T>§marker: PhantomData<&'a mut T>§mode: Mode

The synchronization mode of the lock. This is explicitly passed to let LLVM relate it to the original lock operation.
