LGTM thanks!
also considered if the NonZero* types should be encoded as their wrapped type (i.e. ::Identity == u64), but I'm not sure what implications that would have.
The Identity associated type is used to uniquely identify a type for registering in the type registry, so it is correct to be Self in this case. If it were e.g. u64 it would collide with that u64 primitive type.

The current
TypeInfoimplementation for theNonZero*types is recursive, defining the types as containing a field of itself. This PR fixes the implementation to properly define the inner field as theNonZero*'s wrapped type.I also considered if the
NonZero*types should be encoded as their wrapped type (i.e.<NonZeroU64 as TypeInfo>::Identity == u64), but I'm not sure what implications that would have.NOTE: I've forked this off of b881bfb since our current lockfile contains scale-info = 2.2.
