ActiveKeyStatus

rustc_query_system::query

Enum ActiveKeyStatus 

Source 
pub enum ActiveKeyStatus<'tcx> {
    Started(QueryJob<'tcx>),
    Poisoned,
}
Expand description

For a particular query and key, tracks the status of a query evaluation that has started, but has not yet finished successfully.

(Successful query evaluation for a key is represented by an entry in the query’s in-memory cache.)

Variants§

§

Started(QueryJob<'tcx>)

Some thread is already evaluating the query for this key.

The enclosed QueryJob can be used to wait for it to finish.

§

Poisoned

The query panicked. Queries trying to wait on this will raise a fatal error which will silently panic.
