Struct QueryJob

Source 
pub struct QueryJob {
    pub id: QueryJobId,
    pub span: Span,
    pub parent: Option<QueryJobId>,
    latch: Option<QueryLatch>,
}
Expand description

Represents an active query job.

Fields§

§id: QueryJobId§span: Span

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

§parent: Option<QueryJobId>

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

§latch: Option<QueryLatch>

The latch that is used to wait on this job.

Implementations§

Source§

impl QueryJob

Source

pub fn new(id: QueryJobId, span: Span, parent: Option<QueryJobId>) -> Self

Creates a new query job.

Source

pub(super) fn latch(&mut self) -> QueryLatch

Source

pub fn signal_complete(self)

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
