Moreover it is the only way to encode value. I was aiming to something broader, for example, in array or vector the size is stored in archive, it is size_t and it occupies 64 bit, in case of small data chunks it is complete waste of storage. Is there a way to force all primitive types of choice to use my serialization instead of standard one? I mean is there a way to encode this aforementioned size_t in array serialization without rewriting its implementation?

I was assuming that by "varint" you wanted an integral type of
arbitrary length, yet your example only uses the built-in integral
types. If you only require the latter, and you do not care particularly
about which binary format is used, then I suggest that you try the
transenc serialization archives from:

   https://github.com/breese/trial.protocol

This will select the shortest integral encoding based on the value.

Documentation can be found below, although the transenc part has
not been documented yet:

You can find plenty of examples in the test suites:
