A StaticRow is a C++ type
that can be used to model a row within the static interface (i.e. static_results,
static_execution_state).
A type T is a StaticRow if either of the following is
true:
struct annotated
with Boost.Describe data (i.e., having boost::describe::has_describe_members<T>::value
== true),
and all the described members fulfill the ReadableField
exposition-only concept.
std::tuple instantiation, and all of its
types fulfill the ReadableField
exposition-only concept.
Note that empty Describe structs and empty tuples are valid StaticRows.
A ReadableField is C++ type
that can be used to model a single value in a database row. A type F is a ReadableField
if it is any of the types listed in
this table. The set of readable field types is currently fixed and
can't be extended by the user. If this is something you have interest in,
please file an
issue with your use case to the repo.
The set of allowable types may be extended in future releases, both for fields and for rows.
