Detailed Description

template<typename T, typename = void>
struct PhosphorDBus::HasDBusStreaming< T, typename >

Compile-time check that a type has QDBusArgument streaming operators.

Use in adaptor / marshalling headers to catch a missing operator<< / operator>> definition at build time rather than hitting a runtime "demarshalling function failed" crash.

static_assert(PhosphorDBus::HasDBusStreaming<MyEntry>::value,
    "MyEntry needs QDBusArgument operator<< and operator>>");
