rustc_query_system::query::plumbing

Enum QueryResult

source 
enum QueryResult {
    Started(QueryJob),
    Poisoned,
}
Expand description

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

Variants§

§

Started(QueryJob)

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.

Implementations§

source§

impl QueryResult

source

fn expect_job(self) -> QueryJob
