Struct rustc_query_system::query::plumbing::JobOwner
source · struct JobOwner<'tcx, K>where
K: Eq + Hash + Clone,{
state: &'tcx QueryState<K>,
key: K,
id: QueryJobId,
}
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>

Either gets a JobOwner
corresponding the query, allowing us to
start executing the query, or returns with the result of the query.
This function assumes that try_get_cached
is already called and returned lookup
.
If the query is executing elsewhere, this will wait for it and return the result.
If the query panicked, this will silently panic.
This function is inlined because that results in a noticeable speed-up for some compile-time benchmarks.

fn complete<C>(
self,
cache: &C,
result: C::Value,
dep_node_index: DepNodeIndex
) -> C::Storedwhere
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.
