[−][src]Enum rustc_query_system::query::plumbing::TryGetJob

pub(in query::plumbing) enum TryGetJob<'tcx, D, Q, C> where
    D: Copy + Clone + Eq + Hash,
    Q: Clone,
    C: QueryCache,  {
    NotYetStarted(JobOwner<'tcx, D, Q, C>),
    Cycle(C::Stored),
}

The result of try_start.

Variants

NotYetStarted(JobOwner<'tcx, D, Q, C>)

The query is not yet started. Contains a guard to the cache eventually used to start it.

Cycle(C::Stored)

Trying to execute the query resulted in a cycle.
