Required Methods

fn next_job_id(&self) -> QueryJobId

fn current_query_job(&self) -> Option<QueryJobId>

Get the query information from the TLS context.

fn try_collect_active_jobs(&self) -> Option<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<Diagnostic>>>,
    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.
