[−][src]Struct rustc_middle::ty::query::QueryJob

pub struct QueryJob<CTX> where
    CTX: QueryContext,  {
    pub id: QueryShardJobId,
    pub span: Span,
    pub parent: Option<QueryJobId<<CTX as DepContext>::DepKind>>,
    dummy: PhantomData<QueryLatch<CTX>>,
}

Represents an active query job.

Fields

id: QueryShardJobIdspan: Span

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

parent: Option<QueryJobId<<CTX as DepContext>::DepKind>>

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

dummy: PhantomData<QueryLatch<CTX>>

Implementations

impl<CTX> QueryJob<CTX> where
    CTX: QueryContext, [src]

pub fn new(
    id: QueryShardJobId,
    span: Span,
    parent: Option<QueryJobId<<CTX as DepContext>::DepKind>>
) -> QueryJob<CTX>[src]

Creates a new query job.

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
