Required Methods

Record the map from from local def id to to local def id, on generics_def_id_map field.

Get the previously recorded to local def id given the from local def id, obtained using generics_def_id_map field.

Implementations on Foreign Types

Obtains resolution for a NodeId with a single resolution.

Obtains per-namespace resolutions for use statement with the given NodeId.

Obtains resolution for a label with the given NodeId.

Obtains resolution for a lifetime with the given NodeId.

Obtain the list of lifetimes parameters to add to an item.

Extra lifetime parameters should only be added in places that can appear as a binder in LifetimeRes.

The extra lifetimes that appear from the parenthesized Fn-trait desugaring should appear at the enclosing PolyTraitRef.

Push a remapping into the top-most map. Panics if no map has been pushed. Remapping is used when creating lowering -> impl Trait return types to create the resulting opaque type.
