Expand description
Walk through a function type, gathering all RPITITs and installing a
NormalizesTo(Projection(RPITIT) -> Opaque(RPITIT))
predicate into the
predicates list. This allows us to observe that an RPITIT projects to
its corresponding opaque within the body of a default-body trait method.

Layout§
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...)
attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
