Required Methods

fn next_job_id(self) -> QueryJobId

fn current_query_job(self) -> Option<QueryJobId>

Get the query information from the TLS context.

fn collect_active_jobs(self) -> QueryMap

fn load_side_effects( self, prev_dep_node_index: SerializedDepNodeIndex, ) -> QuerySideEffects

Load side effects associated to the node in the previous session.

fn store_side_effects( self, dep_node_index: DepNodeIndex, side_effects: QuerySideEffects, )

Register diagnostics for the given node, for use in next session.

fn store_side_effects_for_anon_node( self, dep_node_index: DepNodeIndex, side_effects: QuerySideEffects, )

Register diagnostics for the given node, for use in next session.

fn start_query<R>( self, token: QueryJobId, depth_limit: bool, diagnostics: Option<&Lock<ThinVec<DiagInner>>>, compute: impl FnOnce() -> R, ) -> R

Executes a job by changing the ImplicitCtxt to point to the new query job while it executes. It returns the diagnostics captured during execution and the actual result.

fn depth_limit_error(self, job: QueryJobId)
