Expand description

Identifies a particular impl in the source, along with a set of substitutions from the impl’s type/lifetime parameters. The nested vector corresponds to the nested obligations attached to the impl’s type parameters.

The type parameter N indicates the type used for “nested obligations” that are required by the impl. During type-check, this is Obligation, as one might expect. During codegen, however, this is (), because codegen only requires a shallow resolution of an impl, and nested obligations are satisfied later.
