Struct crossbeam_utils::sync::sharded_lock::Shard

source · 
struct Shard {
    lock: RwLock<()>,
    write_guard: UnsafeCell<Option<RwLockWriteGuard<'static, ()>>>,
}
Expand description

A shard containing a single reader-writer lock.

Fields§

§lock: RwLock<()>

The inner reader-writer lock.

§write_guard: UnsafeCell<Option<RwLockWriteGuard<'static, ()>>>

The write-guard keeping this shard locked.

Write operations will lock each shard and store the guard here. These guards get dropped at the same time the big guard is dropped.
