Struct rustc_query_system::query::QueryJob

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

Represents an active query job.

Fields

id: QueryShardJobId

span: 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.

Implementations

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

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

Creates a new query job.

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

Trait Implementations

impl<D: Clone> Clone for QueryJob<D>

fn clone(&self) -> QueryJob<D>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
