pub struct LoggingRustIrDatabase<I, DB, P = DB>
where DB: RustIrDatabase<I>, P: Borrow<DB>, I: Interner,
{ ws: WriterState<I, DB, P>, def_ids: Mutex<IndexSet<RecordedItemId<I>>>, _phantom: PhantomData<DB>, }
Expand description

Wraps another RustIrDatabase (DB) and records which definitions are used.

A full .chalk file containing all used definitions can be recovered through LoggingRustIrDatabase’s Display implementation.

Uses a separate type, P, for the database stored inside to account for Arc or wrapping other storage mediums.

Returns a list of potentially relevant impls for a given trait-id; we also supply the type parameters that we are trying to match (if known: these parameters may contain inference variables, for example). The implementor is permitted to return any superset of the applicable impls; chalk will narrow down the list to only those that truly apply. The parameters are provided as a “hint” to help the implementor do less work, but can be completely ignored if desired. Read more

source§

fn split_projection<'p>( &self, projection: &'p ProjectionTy<I>, ) -> (Arc<AssociatedTyDatum<I>>, &'p [GenericArg<I>], &'p [GenericArg<I>])

Given a projection of an associated type, split the type parameters into those that come from the trait and those that come from the associated type itself. So e.g. if you have (Iterator::Item)<F>, this would return ([F], []), since Iterator::Item is not generic and hence doesn’t have any type parameters itself.
