impl<'tcx> QueryContext for QueryCtxt<'tcx>

fn collect_active_jobs( self, require_complete: bool, ) -> Result<QueryMap<QueryStackDeferred<'tcx>>, QueryMap<QueryStackDeferred<'tcx>>>

Returns a map of currently active query jobs.

If require_complete is true, this function locks all shards of the query results to produce a complete map, which always returns Ok. Otherwise, it may return an incomplete map as an error if any shard lock cannot be acquired.

Prefer passing false to require_complete to avoid potential deadlocks, especially when called from within a deadlock handler, unless a complete map is needed and no deadlock is possible at this call site.

fn start_query<R>( self, token: QueryJobId, depth_limit: bool, compute: impl FnOnce() -> R, ) -> R

Executes a job by changing the ImplicitCtxt to point to the new query job while it executes.

type QueryInfo = QueryStackDeferred<'tcx>

fn jobserver_proxy(&self) -> &Proxy

Gets a jobserver reference which is used to release then acquire a token while waiting on a query.

fn next_job_id(self) -> QueryJobId

fn current_query_job(self) -> Option<QueryJobId>

Get the query information from the TLS context.

fn lift_query_info( self, info: &QueryStackDeferred<'tcx>, ) -> QueryStackFrameExtra

fn load_side_effect( self, prev_dep_node_index: SerializedDepNodeIndex, ) -> Option<QuerySideEffect>

Load a side effect associated to the node in the previous session.

fn store_side_effect( self, dep_node_index: DepNodeIndex, side_effect: QuerySideEffect, )

Register a side effect for the given node, for use in next session.

fn depth_limit_error(self, job: QueryJobId)

impl<'tcx> Copy for QueryCtxt<'tcx>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
