The Frame API should also provide information on the types of the stored collections

[tmadlener]

Currently the Frame API only gives access to the names of the stored collections. It should also be easily possible to get the corresponding type (string), without having to do

auto coll = frame.get(name);
const auto type = coll->getTypeName();

This can be quite costly, as it potentially triggers the unpacking of a collection, simply to get to its type.

making the typename available before unpacking goes rather deep into the stack. The buffers would already need to get that into their interface.

[tmadlener]

With #413 this information would become available from the buffers as string_views, because we need that information internally to retrieve the correct schema evolution function.

ah. thanks for the reminder :-)
