Required methods

fn def_path_str(&self, def_id: DefId) -> String

Get string representation from DefPath.

fn current_query_job(&self) -> Option<QueryJobId<Self::DepKind>>

Get the query information from the TLS context.

fn try_collect_active_jobs(&self) -> Option<QueryMap<Self::DepKind>>

fn try_load_from_on_disk_cache(&self, dep_node: &DepNode<Self::DepKind>)

Load data from the on-disk cache.

fn try_force_from_dep_node(&self, dep_node: &DepNode<Self::DepKind>) -> bool

Try to force a dep node to execute and see if it’s green.

fn load_diagnostics(
    &self,
    prev_dep_node_index: SerializedDepNodeIndex
) -> Vec<Diagnostic>

Load diagnostics associated to the node in the previous session.

fn store_diagnostics(
    &self,
    dep_node_index: DepNodeIndex,
    diagnostics: ThinVec<Diagnostic>
)

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

fn store_diagnostics_for_anon_node(
    &self,
    dep_node_index: DepNodeIndex,
    diagnostics: ThinVec<Diagnostic>
)

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

fn start_query<R>(
    &self,
    token: QueryJobId<Self::DepKind>,
    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.
