pub struct RangeBlockedGuard<'a> {
list: &'a RwLock<RangeBlockedList>,
block: Option<Arc<RangeBlocked>>,
}
Expand description
Keeps a RangeBlocked
alive.
When dropped, removes the RangeBlocked
from its list, and wakes all requests in the waitlist
.
Fields§
§list: &'a RwLock<RangeBlockedList>
List where this blocker resides.
block: Option<Arc<RangeBlocked>>
Option
, so drop()
can take()
it and unwrap the Arc
.
Consequently, do not clone: Must have refcount 1 when dropped. (The only clone must be in
self.list.blocked
, under index self.block.index
.)
