Struct rustc_query_system::query::job::QueryJob[−][src]

pub struct QueryJob<D> {
    pub id: QueryShardJobId,
    pub span: Span,
    pub parent: Option<QueryJobId<D>>,
    dummy: PhantomData<QueryLatch<D>>,
}

Represents an active query job.

Fields

id: QueryShardJobIdspan: Span

The span corresponding to the reason for which this query was required.

parent: Option<QueryJobId<D>>

The parent query job which created this job and is implicitly waiting on it.

dummy: PhantomData<QueryLatch<D>>

Implementations

impl<D> QueryJob<D> where
    D: Copy + Clone + Eq + Hash, [src]

pub fn new(
    id: QueryShardJobId,
    span: Span,
    parent: Option<QueryJobId<D>>
) -> Self[src]

Creates a new query job.

pub(super) fn latch(&mut self, id: QueryJobId<D>) -> QueryLatch<D>[src]

pub fn signal_complete(self)[src]

Signals to waiters that the query is complete.

This does nothing for single threaded rustc, as there are no concurrent jobs which could be waiting on us
