Boost C++ Libraries

Static interface marker type to use Boost.PFR reflection with name-based field matching.

Synopsis

Defined in header <boost/mysql/pfr.hpp>

template<
    class T>
struct pfr_by_name

Description

A marker type that satisfies the StaticRow concept. When used within the static interface, modifies its behavior for the marked type so that Boost.PFR is used for reflection, instead of Boost.Describe. Field matching is performed by name, with the same algorithm used for Boost.Describe structs.

The underlying row type for this marker is T, i.e. underlying_row_t<pfr_by_name<T>> is an alias for T.

The type T must be a PFR-reflectable non-const object type.

This type is only defined if the macro BOOST_PFR_CORE_NAME_ENABLED is defined and set to 1 (requires C++20).
