Struct sc_consensus::shared_data::SharedDataLocked [−][src]
pub struct SharedDataLocked<'a, T> { /* fields omitted */ }
Expand description
Created by SharedData::shared_data_locked
.
As long as this object isn’t dropped, the shared data is held in a mutex guard and the shared
data is tagged as locked. Access to the shared data is provided through
Deref
and DerefMut
. The trick is to use
Self::release_mutex
to release the mutex, but still keep the shared data locked. This means
every other thread trying to access the shared data in this time will need to wait until this
lock is freed.
If this object is dropped without calling Self::release_mutex
, the lock will be dropped
immediately.
Implementations
Release the mutex, but keep the shared data locked.
