enum QueryResult<D> {
    Started(QueryJob<D>),
    Poisoned,
}

Indicates the state of a query for a given key in a query map.

An already executing query. The query job can be used to await for its completion.

Poisoned

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