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.
