* \brief Static interface marker type to use Boost.PFR reflection with positional matching.

* \details
|
|
* 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 position, with the same algorithm used for `std::tuple`.
|
|
* \n
|
|
* The underlying row type for this marker is `T`, i.e.
|
|
* \ref underlying_row_t "underlying_row_t<pfr_by_position<T>>" is an alias for `T`.
|
|
* \n
|
|
* The type `T` must be a PFR-reflectable non-const object type.
|
|
* \n
|
|
* This type is only defined if the macro `BOOST_PFR_ENABLED` is defined and set to `1`.
