> I mentioned this in one of my comments on AVRO-859, but hadn't opened an issue for \
> it yet.  I've been working on a schema resolution implementation for the new value \
> interface in the C library (AVRO-837).  It's similar in structure to the \
> {{avro_resolver_t}} that I had written for the consumer interface.  I'll describe \
> in more detail in later comments (and in the documentation in the source tree), but \
> there are two separate resolver classes for the value interface.  Each is used to \
> wrap an existing value instance, and to create a "view" of that value as if it were \
> an instance of a different schema, and to use the Avro schema resolution rules to \
> translate between the two schemas.  The two classes are needed because the wrapped \
> value might be on the "writer schema" side of the resolution, or on the "reader \
> schema" side.
