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

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

Expand description

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

Variants

Started(QueryJob<D>)

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

Tuple Fields of Started

0: QueryJob<D>

Poisoned

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

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.
