struct JobOwner<'tcx, K>
where K: Eq + Hash + Copy,
{ state: &'tcx QueryState<K>, 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>§key: K

Implementations§

source§

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

source

fn complete<C>(self, cache: &C, 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

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
