Detailed Description

template<typename Value>
struct mp::ReadDestUpdate< Value >

Destination parameter type that can be passed to ReadField function as an alternative to ReadDestEmplace.

Instead of requiring an emplace callback to construct a new value, it just takes a reference to an existing value and assigns a new value to it.

Constructor & Destructor Documentation

template<typename Value >

mp::ReadDestUpdate< Value >::ReadDestUpdate ( Value & value )

inline

Definition at line 121 of file proxy-types.h.

template<typename Value >

template<typename... Args>

Value & mp::ReadDestUpdate< Value >::construct ( Args &&... args )

inline

More complicated case.

If ReadField works by calling construct(), need to reconstruct m_value in place.

Value & mp::ReadDestUpdate< Value >::update ( UpdateFn && update_fn )

Simple case. If ReadField works by calling update() just forward arguments to update_fn.
