Struct JobOwner 

Source 
struct JobOwner<'tcx, K, I>
where
    K: Eq + Hash + Copy,
{
    state: &'tcx QueryState<K, I>,
    key: K,
}
Expand description

A type representing the responsibility to execute the job in the job field. This will poison the relevant query if dropped.

Fields§

§state: &'tcx QueryState<K, I>§key: K

Implementations§

Source§

impl<'tcx, K, I> JobOwner<'tcx, K, I>
where K: Eq + Hash + Copy,

Source

fn complete<C>( self, cache: &C, key_hash: u64, result: C::Value, dep_node_index: DepNodeIndex, )
where C: QueryCache<Key = K>,

Completes the query by updating the query cache with the result, signals the waiter and forgets the JobOwner, so it won’t poison the query
