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

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

Expand description

The result of try_start.

Variants

NotYetStarted(JobOwner<'tcx, D, 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.

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.
