I must still not be understanding what you meant in your
original comment. Because in my view, cereal and binary are
*exactly* designed for that use, and do it extremely well.

The only place where a particular "constructor-by-constructor"
approach is built in is in the facilities for automated generation
of parsers using generic techniques. But when writing parsers
directly, you have full flexibility, and a powerful set of
built-in tools to back you up.
