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

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

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, Q>>

Implementations

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

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

Creates a new query job.

pub(in query) fn latch(
    &mut self,
    id: QueryJobId<D>
) -> QueryLatch<D, Q>[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
