AbstractedWaiter

rustc_query_impl::job

Struct AbstractedWaiter 

Source 
struct AbstractedWaiter {
    span: Span,
    parent: Option<QueryJobId>,
    resumable: Option<(QueryJobId, usize)>,
}
Expand description

This abstracts over non-resumable waiters which are found in QueryJob’s parent field and resumable waiters are in latch field.

Fields§

§span: Span

The span corresponding to the reason for why we’re waiting on this query.

§parent: Option<QueryJobId>

The query which we are waiting from, if none the waiter is from a compiler root.

§resumable: Option<(QueryJobId, usize)>
